Temperature and pressure are fundamental physical parameters in the field of materials science, making their monitoring utmost significance for scientists engineers. Here, NaSrY(MoO4)3:0.02Er3+/0.01Tm3+/0.15Yb3+ nanophosphor is developed as an optical sensor material. Under 975 nm laser excitation, upconversion characteristics detection performance multifunctional sensing platform temperature (vacuum) investigated. We have successfully a novel that enables temperature. This utilizes thermally coupled levels (TCLs) non-TCLs Er3+ Tm3+ to achieve ratiometric detection. The multimodal based on TCLs realized by using different emission bands double centers, which makes it possible self-referencing measurement modes. These results indicate promising candidate sensors, our findings suggest potential strategies modulating properties luminescent doped with rare-earth ions.

Phase transition-based thermometers, which are widely known for their remarkable sensitivity to temperature changes, exhibit a narrow range owing the stoichiometry of host material. This limits applicability optical sensors utilizing structural phase transitions. In this study, we introduce co-doping method modulating properties luminescent thermometers influence transition temperature. We demonstrate that by adjusting ionic radius dopant and its concentration, can be finely tuned across broad spectrum. The proposed technique enables customization with enhanced sensitivities practical ranges tailored specific user requirements. study represents crucial advancement towards development personalized luminescence thermometers.
