Transition-Metal Ions in Nd-Doped Glasses: Spectra and Effects on Nd Fluorescence

Concentration quenched luminescence and energy transfer analysis of Nd ions doped Ba-Al-metaphosphate laser glasses

This paper reports the dopant ion (Nd) concentration effects on its luminescence properties in a new glass system based on barium-alumino-metaphosphates. Amongst the studied concentrations range of 0.276 – 13.31 x 10 ions/cm, the glass with 2.879 x 10 ions/cm (1 mol%) Ndconcentration shows intense NIR emission from F3/2 excited state, followed by a decrease in emission intensity for further inc...

Analysis of upconverted UV fluorescence dynamics in Nd doped ZBLAN glasses

Rare-earth doped low phonon glasses are attractive media for unconverted, short wavelength fiber lasers. Fluorozirconate glass (ZBLAN) is one of the most popular representatives of this type of materials. Lasing in the visible part of spectrum has been reported in various upconversion pumped RE doped ZBLAN systems [1-2], but till now generation in the ultra-violet (UV) has only been observed in...

Optical Absorption and Fluorescence Spectral Analysis of Nd 3 + Doped Bismuth Boro - Silicate Glasses

Glasses having compositions 20B2O3.(79.5-x) Bi2O3.xSiO2 (10 ≤ x ≤ 40, mol%) doped with 0.5 mol% of Nd ions were prepared by melt quench technique. The amorphous nature of the glasses was confirmed by X-ray diffraction studies. The spectroscopic properties of Nd ions in borate bismuth silicate glasses as a function of bismuth oxide were investigated using optical absorption and fluorescence spec...

Optical 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...
