Up-Converting K₂Gd(PO₄)(WO₄):20%Yb³⁺,Ho³⁺ Phosphors for Temperature Sensing.

ABSTRACT: Inorganic luminescent materials that can be excited with NIR radiation and emit in the visible spectrum have recently gained much scientific interest. Such materials can be utilized as anti-counterfeiting pigments, luminescent thermometers, bio-imaging agents, etc. In this work, we report the synthesis and optical properties of K₂Gd(PO₄)(WO₄):Ho³⁺ and K₂Gd(PO₄)(WO₄):20%Yb³⁺,Ho³⁺ powders. The single-phase samples were prepared by the solid-state reaction method, and the Ho³⁺ concentration was changed from 0.5% to 10% with respect to Gd³⁺. It is interesting to note that under 450 nm excitation, no concentration quenching was observed in K₂Gd(PO₄)(WO
