Abstract The oxidation behavior, optical properties, and mechanism of Mg 0.27 Al 2.58 O 3.73 N (MgAlON) transparent ceramics in the air at high temperatures were systematically investigated this work. Above 1000°C, rapid loss MgAlON can be attributed to scattering refraction light caused by generated α ‐Al 2 3 second phase, cracks, pores. Non‐isothermal isothermal methods employed study kinetics ceramics, which obeyed parabolic law. rates 1300°C, 1400°C, 1500°C determined 0.048, 1.097, 7.421 mg /cm 4 ·h, respectively, apparent activation energy was calculated 586.63 kJ/mol. This work revealed guides its practical applications.

Dual-Phase Glass Ceramics Containing ZnGa₂O₄:Cr³⁺ and NaYF₄:Yb³⁺,Er³⁺ Nanocrystals for Dual-Mode Optical Thermometry

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(33), P. 15388 - 15397

Published: Aug. 9, 2024

Currently, developing luminescent materials for dual-mode optical thermometry has been becoming a rising topic, and concurrent temperature-sensitive parameters hold the key. Still, it is serious challenge, since distinct activators are generally needed energy transfer (ET) processes among inevitably occur, further leading to severe luminescence quenching. Herein, spatial separation strategy proposed designing dual-phase glass ceramics (GCs) containing ZnGa2O4:Cr3+ NaYF4:Yb3+,Er3+ nanocrystals (NCs) thermometry, in order integrate diversified into one. Structural, morphological, characterizations examined verify partition of Cr3+ ZnGa2O4 Er3+ NaYF4 lattice GC. Benefiting from such strategy, adverse ET between could be cut off GC, contributing downshifting (DS) upconversion (UC) luminescence. Furthermore, performed based on lifetime fluorescence intensity ratio (FIR) Er3+, with high relative sensitivities 0.95% K–1@450 K 1.24% K–1@303 K, respectively. It evidenced that GC holds great potential this work also offers prospective pathway expanding practical applications materials.
