Spectroscopic Investigation of The Optical Properties of Rare Earth Doped Phosphate and Tellurite Glasses
Improving the up-conversion efficiency is the key issue in rare earth doped glasses. The quantum efficiency, optical gap, radiative transition rate and lifetimes of excited states are greatly influenced by the optical properties of the host material, ligand field, multi-phonon relaxation processes, impurities, temperature and concentration of rare earth ions. This presentation gives a panoramic...
متن کاملOptical Properties of Ho3+ Doped in Tellurite Glass
We visit the standard procedure for analyzing the optical spectrum of Ho doped tellurite glass has been studied. The glass was formed using a composition 79% Te O2 + 20% Li2 CO2 + 1% Ho O2. I density and refractive index were measured and used to calculate various physical properties such as, rare earth concentration, mean atomic volume, electric polarization, ionic radius, molar refractivity, ...
متن کاملOptical spectroscopy of Eu3+ doped zinc borate glasses
Zinc borate binary glasses of composition 4Zn0.3B,03 undoped and doped with 0.5% mol of Eu3' were prepared from the melt giving rise to samples of excellent optical quality. In the present work we use the spectroscopic properties of the Eu3' to obtain information about the structural and dynamic features of our system. Different optical techniques such as site selection, excitation spectroscopy...
متن کاملOptical properties of Nd doped Bi2O3-PbO-Ga2O3 glasses.
The optical properties of a new family of neodymium doped BPG (Bi2O3-PbO-Ga2O3 ) glasses are presented. We measured a high refractive index, of 2.5, and a transmission cutoff in the far infrared at 8microm. Three intense emission bands are observed centered at 877nm, 1066nm and 1341nm. The emission cross-section is 10 -20 cm 2 and the total spectral linewidth is 30nm at 1066nm. The Judd-Ofelt p...
