A three-mode self-referenced optical thermometry based on up-conversion luminescence of Ca2MgWO6:Er3+,Yb3+phosphors

YunCheng Jiang et al.

Summary: A series of Ca2MgWO6:xEr3+, yYb3+ phosphor samples were synthesized through high temperature solid-state reaction method for optical thermometry. These samples showed intense up-conversion luminescence when excited by 980 nm laser, with enhanced emissions by addition of Yb3+ ions. The phosphors demonstrated a dual-mode temperature sensor and superior thermal stability, indicating potential applications for self-referenced optical thermometry.
