A Spectroscopic Analysis of Blue and Ultraviolet Upconverted Emissions from Gd3Ga5O12:Tm3+, Yb3+ Nanocrystals

The spectroscopic behavior of gadolinium gallium garnet (Gd3Ga5O12, GGG) nanocrystals codoped with 1% each of Tm3+ and Yb3+ prepared via a solution combustion synthesis procedure was investigated. Initial excitation of the codoped nanocrystals with 465.8 nm (into the 1G4 state) showed a dominant blu...
