Violet-blue emissions due to frequency up-conversion in Nd3+-doped fluoroindate glasses
(1997-06-01)
We report the observation of intense frequency up-conversion in Nd3+-doped fluoroindate glasses pumped by the second harmonic of a cw mode-locked Nd: YAG laser. Mechanisms for generating the observed emissions are discussed.

Energy transfer assisted frequency upconversion in Ho 3+ doped fluoroindate glass
(2002-02-01)
Experimental results are reported which show a strong evidence of energy transfer between Ho 3+ ions in a fluoroindate glass excited by a pulsed laser operating at 640 nm. We identified the origin of the blue and green ...

Enhanced frequency upconversion in Er3+ doped fluoroindate glass due to energy transfer from Tm3+
(2002-12-01)
Energy transfer processes between Er3+ and Tm3+ were investigated examining the frequency upconversion emissions in a fluoroindate glass pumped at 790 nm. A 60-fold enhancement in the emission at ≈670 nm originating from ...
Energy transfer between Pr3+ ions in a fluoroindate glass
(1998-06-01)
The efficiency of energy transfer (ET) between Pr3+ ions in a fluoroindate glass is determined. ET rates, WET, were determined for dilute samples and the results show a dependence of WET on the Pr3+ concentration. ET ...
New compositions of fluoroindate glasses with higher chemical resistance
(Soc Brasileira Quimica, 1998-05-01)
The chemical resistance of fluoride glasses in aqueous solution is a very important factor concerning the technological applications of these materials. In this paper, glasses in the systems In-Ba-Mg and In-Ba-Zn-Sr-Mg ...
Concentration Dependence of the Infrared Photoluminescence of Pr3+ in Fluoroindate Glasses
(Ieee, 2016-01-01)
Infrared photoluminescence properties are investigated for Pr3+ containing fluoroindate glasses with formula (mol% compositions) (99-x)[ 40InF(3)-20SrF(2)-20BaF(2)-20ZnF(2)]:xPrF(3) (x= 0.1, 0.2, 0.5, 1.0 and 2.0 mol%). ...

Infrared photoluminescence properties are investigated for Pr3+ containing fluoroindate glasses with formula (mol% compositions) (99-x)[40InF3-20SrF2-20BaF2-20ZnF2]:xPrF3 (x= 0.1, 0.2, 0.5, 1.0 and 2.0 mol%). Different ...
New compositions of fluoroindate glasses with higher chemical resistance
(Sociedade Brasileira de Química, 1998-06-01)
In this paper, glasses in the systems In-Ba-Mg and In-Ba-Zn-Sr-Mg were water leachead at 80ºC showing surface degradation after 72 hours of leaching. The extent of such degradation is determined by the solubility and the ...
