Mn doped ZnO films with glaszes doping concentration were synthesized by sol gel method using the spin coating technique.

Optical Properties of Erbium Doped Tellurite Glasses

The films had hexagonal shaped grains and the evaluated grain size varied in the range of 20 – 48 nm. Forbidden band Eg was obtained from absorption spectrum. It has a wide range of applications. These films achieve tunable band gap characteristics by means of changing the dopant tellutite.

The absorption peaks around cm-1 and cm-1 are related to the stretching vibrations of the hydroxyl group participating in the strong metal and hydrogen bonding, respectively. Concentration dependent chemical durability, thermal stability and spectroscopic properties, Journal of Non-Crystalline Solids. The improved tellurtie and structural properties suggest that the studied glasses are potential candidates glases nanophotonic devices.

The significant enhancement in the luminescence with the increase of AgCl is ascribed to the local field enhancement induced by Ag0 surface plasmon resonance and the energy transfer from fluorescent Ag0?
