“…Several works have examined the UC emission of Yb 3þ and Tm 3þ doped Y 2 O 3 . [19][20][21][22][23] They are mainly focused on strong blue and weak red emission of Tm 3þ ions. Up until now, the green UC region has been mentioned (535 to 560 nm) only in a few studies.…”

Green emission lines, in addition to the blue and the red, were observed upon 980 nm excitation in yttrium oxide (Y 2 O 3) nanopowder codoped with Yb 3þ and Tm 3þ , synthesized by the chemical combustion method. Upconversion emission studies suggest that the number and characteristics of the green lines are influenced by the annealing temperature as well as by the Yb 3þ ∕Tm 3þ concentration ratio, opening possibilities for new customized applications. The chromaticity properties of the upconversion spectra were quantified by the Commission Internationale de l'éclairage coordinate analysis.
