In light of this, versatile 2D lead-free (CH₃NH₃)₂CuCl₄ (CuP), Co-infused (CH₃NH₃)₂CuCl₄ (CCuP), and Ni-infused (CH₃NH₃)₂CuCl₄ (NCuP) hybrid perovskites are synthesized via the sono-coprecipitation method with a potential compositional engineering approach and dopant effects studied using different characterization tools. The diffractograms reveal that the partial dopant Co and Ni insertion at the “B”- site of the (CH₃NH₃)₂CuCl₄ crystal effectively modified the optical bandgaps from 2.29 to 2.16 eV. The perovskites display a spectrum of colors (yellow, orange, red, and dark brown) accompanied by thermal-induced lattice expansion, phase transition, and electron–phonon interactions. Lattice dynamics, structural and optical features are explored to gain insights into the effects of cation infusion on thermochromism and other characteristics. The <i>in situ</i> temperature-dependent powder VT-XRD, VT-Raman, and VT-UV–vis spectra were analyzed in heating and cooling cycles. Notably, it is discovered that the degree of thermochromism is possibly depending on the dopant used. Repetitive heating–cooling cycles showed minimal fluctuation in VT-XRD, demonstrating excellent stability with thermochromic properties. Cyclic voltammetry was performed for the first time on these copper-based perovskites to investigate the electrochemical activity with plausible oxidation and reduction reactions. Dielectric characteristics and AC conductivity at different temperatures have been studied. A sustainable post-treatment technique resulted in excellent stability, crystallinity, and tailored grain boundaries at the nanoscale using a solvent with a lower Gutmann donor number and Kamlet–Taft parameter. The present study provides insights into the basic principles governing thermochromic behavior and possibilities for the thoughtful development of perovskites. These are believed to be the optimal results for the systems that have been reported to date.</p>","PeriodicalId":29803,"journal":{"name":"ACS Applied Optical Materials","volume":"3 8","pages":"1777–1799"},"PeriodicalIF":3.8,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144885197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Micrometer-sized crystalline waveguides allow such interactions to be achieved at relatively low energies by taking advantage of the confinement of light. The materials selected to achieve these phenomena in the present work are from the titanyl phosphate family. The chosen architecture is a micrometric layer of KTiOAsO₄ (KTA) grown on a KTiOPO₄ (KTP) substrate forming a planar waveguide in a first step. These two isostructural materials have a low lattice parameter mismatch (around 2%), making it possible to achieve high-quality epitaxial growth. Due to the refractive index of KTA being higher than that of KTP (Δ<i>n</i> ≈ 0.043 at 1500 nm), this couple of materials could allow light to be guided in the deposited layer. To grow the KTA film, the chosen technique is pulsed laser deposition (PLD), which allows a nonlinear complex oxide layer of optical quality to be grown. In this study, we show that the growth is well oriented for layers with a thickness up to 200 nm after deposition under 32 mTorr of oxygen and a laser fluence of 0.8 J cm^–2, forming epitaxial layers. Then, after annealing at 650 °C for 14 h, the crystal state is improved as well as the surface. However, our calculations show that the layer’s thickness has to be equal to 1.68 μm to achieve second-harmonic generation (SHG) at telecom wavelengths, which is the next step of this research. In this study we demonstrate the feasibility of KTA epitaxy over KTP by PLD with good epitaxial quality, good orientation, and theoretical phase-matching conditions for a planar KTA waveguide.</p>","PeriodicalId":29803,"journal":{"name":"ACS Applied Optical Materials","volume":"3 8","pages":"1651–1656"},"PeriodicalIF":3.8,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144885147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
