In order to break through the limitations of application traditional temperature measurement technology, non-contact optical sensing material with good sensitivity is one current research hotspots. Herein, a series Dy3+ and Mn4+ co-doping Mg3Ga2SnO8 fluorescent materials were prepared successfully, crystal structure, phase purity, morphology synthesized phosphors comprehensively investigated, as well their photoluminescence properties, energy transfer, high-temperature thermal stability. The two pairs independent thermally coupled levels ions in are utilized realize dual-mode detection excellent performance. On hand, based on different ionic level transitions 4F9/2→6H13/2 2Eg→4A2g responding differently temperature, emission bands 577 nm 668 chosen construct fluorescence intensity ratio thermometry, maximum 1.82 %K−1 was achieved at 473 K. other strong dependence lifetime Mg3Ga2SnO8:0.06Dy3+,0.009Mn4+, thermometry constructed 2.75 Finally, Mg3Ga2SnO8: 0.06Dy3+,0.009Mn4+ sample realizes high wide range, indicating that has promising applications measurement.

A structural design strategy was employed to develop NaGd2Ga2InGe2O12:Sm3+ (NGGIG:Sm3+) garnet phosphors, optimizing the local coordination environment enhance luminescence performance. By tailoring site occupation, Sm3+ ions were incorporated into an asymmetric crystal field, where a statistical probability model confirmed that ∼97% of reside in distorted environments, promoting electric dipole(ED) transitions. The phosphors exhibit high red-to-orange (R/O) intensity ratio 2.97, contributing enhanced red emission. CIE chromaticity coordinates (0.61, 0.39) indicate significant shift toward region, and retain over 70% their at 400 K, demonstrating good thermal stability. These characteristics make NGGIG:Sm3+ promising candidate for high-performance solid-state lighting applications, highlighting effectiveness engineering structures efficiency
