Sound, Force and Light Induced Emissions from Er³⁺-Mn²⁺ Doped ZnS/CaZnOS Heterostructure for Remote Temperature Monitoring via Photo- and Mechanoluminescence.

ABSTRACT: Mechanoluminescence (ML) is a powerful phenomenon that enables light generation induced with mechanical or acoustic waves, and remote temperature sensing via luminescence thermometry techniques. In this work, the multi-functional, ML-active materials based on Er³⁺ and Mn²⁺ co-doped ZnS/CaZnOS heterostructure are developed for remote temperature monitoring and visual sensing of force and sound. The material exhibits characteristic photoluminescence (PL) under UV and NIR (up-conversion) excitation, with energy transfer from Er³⁺ to Mn²⁺ influencing the emission color. The effects of force-to-light conversion are studied in detail by measuring the ML intensity versus the applied power for Er³⁺ and Mn²⁺ emission in the single-do
