## Abstract Largeโscale zinc oxide (ZnO) nanotetrapods have been grown on pโtype Si (111) substrate by oxidizing zinc pieces in air by thermal evaporation technique without the presence of any catalyst. The size and morphology of the nanostructures was found to depend on experimental parameters. Th
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
