This work investigates a stable Sn4+-based Cs2SnCl6 system through gradient HCl-mediated approach to address Sn2+ instability. The influence of HCl concentration shows clear effects on crystal growth, defects, and optoelectronic properties. The optimized 0.048 mol/L HCl sample shows a well-defined truncated octahedral morphology, with better structural ordering and a sharper A1g Raman mode. It has strong UV absorption of around 3.83 eV, and better photoluminescence with a PLQY of ~27.3%. The corresponding large Stokes shift (~0.6 eV) owing to controlled defect states that balance radiative and non-radiative recombination pathways. Significantly, this sample displays n-type conductivity with enhanced carrier transport, an unreported electrical behavior in Cs2SnCl6, with a carrier concentration (1.35 × 1014 cm−3) and resistivity (0.55 × 105 Ω cm). This material shows good structural stability over 200 days at ambient conditions and thermally stable up to 600°C. Variation in HCl concentration controls the growth of [SnCl6]2− octahedra, which affects both morphology and defect states, contributing better material performance.

Benefiting from their intrinsic merits, including high fluorescence quantum yield (FQY), tunable photophysical properties, excellent photochemical stability, and facile structural functionalization, PDIs have shown outstanding performance in photodynamic therapy (PDT) and photothermal therapy (PTT). However, the biomedical translation of PDIs still faces critical bottlenecks: insufficient water solubility and severe aggregation-caused quenching (ACQ) effect derived from strong intermolecular π–π stacking, limited tissue penetration depth from short-wavelength absorption/emission, tumor microenvironment hypoxia that restricts type II PDT efficacy, and unsatisfactory photothermal conversion efficiency (PCE) of conventional PDI derivatives for PTT. This review systematically summarizes the research progress of PDIs in biomedical fields, focusing on molecular design strategies for spectral redshift, water solubility enhancement, and phototherapeutic performance optimization. Meanwhile, the structure–property relationships of PDI derivatives are elaborated in depth from the perspective of molecular orbital engineering and aggregation state regulation. Finally, existing challenges and future development directions in biomedical translation are discussed to provide guidance for the rational design of high-performance PDI-based diagnostic and therapeutic agents.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"41 6","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148145315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This strategy eliminates the need for toxic reagents or derivatization steps. The complex had a 1:1 stoichiometry and a high binding constant of 2.6 × 103 L/mol.

The present study evaluates the viability of present glasses as transparent shielding materials. The glasses are prepared using the melt-quenching technique. The amorphous nature is verified using X-ray diffraction (XRD) spectroscopy. The optical characteristics are evaluated using UV–Vis absorption spectroscopy, while the radiation shielding competence is experimentally quantified using a narrow beam NaI (Tl) detector setup at 356, 511, 662, 1173, and 1330 keV. The incorporation of BaO, PbO2, and Pr6O11 increased the density of the glasses from 4.252 g cm−3 to a peak of 4.898 g cm−3. The UV–Vis spectra exhibited four distinctive absorption peaks at ~446, 472, 484, and 582 nm, confirming the active presence of Pr3+ ions. The addition of BaO, PbO2, and Pr6O11 facilitated the formation of non-bridging oxygens, which resulted in a decrease in the optical band gap (Eg) from 2.467 eV down to 2.138 eV. The experimental radiation shielding data confirmed that the highest concentration of BaO, PbO2, and Pr6O11 improved the attenuation coefficients across the tested energy spectrum.
