## Abstract The structural and optical features of gallium gadolinium garnet (GGG) nanopowders doped with neodymium were investigated. Nanopowders of GGG:Nd were prepared by modified solβgel method using acetic acid as complexing agent. This way permitted to incorporate large amounts of dopant (up
Crystal growth, optical absorption, emission spectra and fluorescence decay times of calcium-and vanadium-doped Gd,Ga,O,, garnet are reported. The observed optical spectra are assigned to V4+ ions in octahedral and tetrahedral sites. A broad red luminescence in the 600-800 nm region is shown to be d
