Development of SrWO₄:Ho³⁺/Yb³⁺ green phosphor for optical thermometry application

Abstract

SrWO4: Ho3+/Yb3+ phosphor exhibiting down-conversion and up-conversion photoluminescence for green light generation and optical thermometry applications.

Barium molybdate up-conversion nanoscale particles with IR-LED chip, temperature sensing, and anti-counterfeiting applications

“…Among various inorganic materials, the molybdate-based material ABO 4 (A = Ca, Ba, Sr and B = W, Mo) is widely used in down-conversion phosphors due to its chemical stability and the property of transferring energy absorbed in the UV and visible light regions to activator ions, making it a lanthanide ion. 16–20 It is suitable as a base material for rare-earth (RE)-doped phosphors. Jiang et al introduced the structure and emission characteristics of a Ca 2 MgWO 6 :Er 3+ ,Yb 3+ UC phosphor synthesized by sintering at high temperature using a solid-state reaction (SSR) method and suggested that it can be applied to optical thermometry.…”
