High-efficiency upconversion luminescence and enhanced sensitivity temperature sensing behavior in Ho3+/Yb3+ doped yttrium Oxysulfide phosphors

High-efficiency upconversion luminescence and enhanced sensitivity temperature sensing behavior in Ho3+/Yb3+ doped yttrium Oxysulfide phosphors

A series of Y2O2S: 0.25 % Ho3+/x%Yb3+ (where x = 4, 6, 8, and 10) phosphors were synthesized by using a chemical co-precipitation method, and their temperature sensing properties were systematically investigated. The upconversion luminescence (UCL) spectra of the samples were recorded under 980 nm l...
