Understanding its melt properties and structure is essential for elucidating crystal-growth mechanisms and guiding process design. We measured the density, viscosity, and surface tension of 20 at% Er:YAG melt using aerodynamic levitation, established temperature dependences, and validated the results through molecular dynamics (MD) simulations. Furthermore, we build MD models of 20 at% and 50 at% Er:YAG melts in LAMMPS and compute radial distribution functions and coordination numbers for Y, Er and Al. The results show that the mean bond length remains nearly constant at high temperature, whereas the local structure becomes progressively more disordered with increasing temperature, confirming temperature as a key control parameter for short-range order. We also find that Er3+ can readily substitute for Y3+ in the melt, which helps explain the observed temperature dependences of the macroscopic density and viscosity. Finally, using the measured density, viscosity and surface tension, we develop a two-dimensional axisymmetric steady-state model to systematically analyse how the rotation rate, pulling rate and insulation-structure parameters (thickness, height and aperture) affect the temperature field, flow field and the shape of the solid–liquid interface. Simulations indicate that using Er:YAG-specific parameters, rather than YAG data, leads to markedly different flow patterns and interface morphologies under varying growth conditions. This difference implies that substituting YAG parameters for Er:YAG can introduce substantial errors in growth simulations, underscoring the importance of measuring high-temperature properties of Er-doped YAG melts for accurate modelling of crystal growth. Under the optimised conditions suggested by the simulations, we grow a 20 at% Er:YAG single crystal with dimensions of 80 mm × 100 mm.","PeriodicalId":70,"journal":{"name":"CrystEngComm","volume":" 23","pages":" 3649-3665"},"PeriodicalIF":2.6,"publicationDate":"2026-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148247653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In its application media – paints and printing inks – the pigment is not dissolved, but finely dispersed; hence, the crystal structure is maintained and has a strong effect on the properties. Hitherto, the crystal structure of P.R.5 has not been known, because the pronounced insolubility in water and in common organic solvents hampers the growth of single crystals for X-ray analysis. Since structure determination from powder data failed as well, the structure was determined by 3-dimensional electron diffraction (3D-ED). P.R.5 crystallises in the triclinic space group P<img> (Z = 2), with layers of largely planar molecules. The structure was later confirmed by single-crystal X-ray analysis of a tiny crystal. The structure contains a void of about 36 Å3 between the molecules—a feature unprecedented in any known commercial organic pigment, as such voids deteriorate the packing efficiency, the lattice energy, and the application properties. To address these drawbacks, crystal engineering strategies were applied. First, lattice-energy minimisations guided the selection of potential derivatives and solid solutions. Several promising solid solutions were then synthesised and analysed by X-ray powder diffraction and single crystal analysis, and, indeed, according to the lattice-energy minimisations, the void could be filled.","PeriodicalId":70,"journal":{"name":"CrystEngComm","volume":" 23","pages":" 3558-3578"},"PeriodicalIF":2.6,"publicationDate":"2026-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/ce/d6ce00140h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148247646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the relatively weak radioluminescence intensity of single rare-earth-doped LiLuF4 crystals has constrained their practical applications. In this work, Ni2+ co-doped LiLuF4:Tb microcrystalline scintillators are synthesized via a hydrothermal method. The incorporation of heterovalent Ni2+ ions effectively enhanced both the radioluminescence and thermoluminescence intensities of LiLuF4 microcrystals. After doping with 3 mol% Ni2+ ions, the radioluminescence intensity increased by 125.34%. The X-ray detection limit of LiLuF4:Tb,Ni reaches 3.7966 nGy s−1, which is considerably lower than the medical imaging requirement of 5.5 μGy s−1.

Structural analyses reveal that pH, together with the metal center and auxiliary ligand, influences ligand deprotonation, metal–ligand connectivity, and supramolecular packing, thereby leading to distinct 1D, 2D, and discrete structural motifs. All compounds exhibit excitation-wavelength-dependent photoluminescence, enabling tunable emission across the visible region and quasi-white-light-like emission. Density-of-states calculations indicate ligand-dominated electronic structures, with emission originating from intrinsic ligand luminescence and π–π-interaction-assisted interligand charge-transfer transitions.

In these materials, crystal growth is not merely a preparative step but a thermodynamic boundary condition that establishes chemical potentials, defect populations, polytype stability, and access to metastable phases. As a result, synthesis strongly influences the structural and defect landscape from which collective electronic behavior emerges. In this Review, we develop a unified thermodynamic–kinetic framework that connects growth conditions to phase stability, defect energetics, and microstructure. We examine how chemical-potential constraints define stability windows, how supersaturation and mass-transport regimes govern nucleation and morphology, and how nonequilibrium pathways enable kinetic trapping and polymorph selection. Bulk and thin-film synthesis approaches, including chemical vapor transport (CVT), flux growth, physical vapor transport (PVT), solvent-assisted crystallization, chemical vapor deposition (CVD), and molecular beam epitaxy (MBE), are placed within a common thermodynamic–kinetic map to clarify how distinct growth regimes produce characteristic disorder profiles and structural phases. By explicitly linking synthesis variables to charge-density-wave order (CDW), superconductivity, band topology, and correlation effects, this Review highlights crystal growth as a central parameter in shaping the effective electronic Hamiltonian realized experimentally. This perspective provides a physically grounded framework for improving reproducibility and guiding deterministic control of emergent quantum phases in layered materials.","PeriodicalId":70,"journal":{"name":"CrystEngComm","volume":" 22","pages":" 3414-3434"},"PeriodicalIF":2.6,"publicationDate":"2026-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148193679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comprehensive characterization revealed that the as-prepared Fe1Co1Zn2-ZIF maintained the typical rhombic dodecahedral morphology of ZIF-67, whereas the ternary metal doping induced a roughened surface decorated with nanoparticles, thereby increasing the specific surface area and the exposure of active sites. Electrochemical tests demonstrated that the catalyst with a Fe : Co : Zn molar ratio of 1 : 1 : 2 (Fe1Co1Zn2-ZIF) exhibited optimal OER performance in 1 M KOH, requiring an overpotential of only 366 mV to achieve a current density of 10 mA cm−2, comparable to that of commercial RuO2. It also showed the lowest Tafel slope (78.7 mV dec−1). Furthermore, this catalyst demonstrated superior charge transfer capability (Rct = 12.52 Ω) and good stability, maintaining its catalytic activity for approximately 28 hours. The excellent performance is attributed to the synergistic effect among Fe, Co, and Zn, where Zn incorporation modulates metal dispersion, and Fe doping optimizes the electronic structure and facilitates charge transport.
