Cross-relaxation and energy transfer processes in praseodymium-doped gadolinium gallium garnet (Gd3Ga5O12:Pr3+) bulk and nanocrystalline systems
The luminescence properties of singly-doped Pr 3+ and Pr 3+ /Yb 3+ co-doped nanocrystalline gadolinium gallium garnet (GGG, Gd 3 Ga 5 O 12 ) are investigated. Dominant blue/green emission emanating from the 3 P 0 [arrow right] 3 H 4 and 3 P 0 [arrow right] 3 H 6 transitions was observed after excita...
