Paper Abstract

Until now, all studies were done over the semiconductor glasses doped with CdSxSe1-x, in which the microcrystallite phase was grown into a vitreous silica matrix. Our study was made as for growing microcrystallites of CdSxSe1-x into a vitreous aluminophosphate matrix. In the first step, the samples of semiconductor glass were obtained by melting the raw materials batch and then by adding sulphur selenium and cadmium into the molten glass. In the second step, the resulted glass was annealed in order to bring about the microcrystallite nucleation and growing process. Both linear and non-linear optical properties are deeply influence by the microcrystallite size, which, on its turn is determined by the duration and temperature of the annealing treatment. By means of a spectrophotometer (SPECORD M- 42), were drawn absorption, transmission and fluorescence spectra, in visible domain. From the shape and the absorption edge of these spectra, we are able to characterize the microcrystallite growing process. From these spectra it can be observed a shift of the absorption edge to red which depends on the microcrystallite size.
