Combustion synthesized Gd 2 O 3 : Er 3+ /Yb 3+ nanocrystalline phosphor has been developed and used as a temperature sensor. Frequency upconverted emissions from two thermally coupled excited states 2 H 11/2 and 4 S 3/2 of Er 3+ centered at 523 and 548 nm in the phosphor pumped by NIR source were re
