Piezooptical effects in the tellurite glasses doped by europium and gold

Original language description

We present the temperature dependence of piezooptical coefficients for three samples of TeO2-GeO2-PbO glasses doped with 0.5% of Eu2O3, 0.5% and 1% of Au2O3, after different thermoannealing times. We have established that there exist two temperatures singularities - minima in the range 655-695 K and maxima - at 850 K. It is crucial that for the glasses annealed during 61 h, at temperatures about 850 K, the anomaly of piezooptical coefficient disappears. Simultaneously the minima within the range 655-695K changed depending on the duration of the thermoannealing which leads to low temperature shift of the minima. Towards lower temperature the piezooptical maxima occurs around 850 K and disappears after the increase of the annealing time. It is also crucial that the values of the piezooptical coefficients decrease with the enhancement of the thermoannealing. The observed temperature dependence with the piezooptical coefficients has a good correlation with the temperature dependences of t

Piezo-optické efekty v ?tellurite? sklu legovaném europiem a zlatem

Czech description

Představujeme teplotní závislost piezo-optických koeficientů pro 3 vzorky TeO2-GeO2-PbO skla legovaného 0,5 % Eu2O3, 0,5 % a 1 % Au2O3 v různých ?thermoannealing? časech. Zjistili jsme, že existují dvě singularity teploty, minima v rozmezí 655-695 K a maxima při 850 K. To je kritické pro skla žíhaná během 61 h při teplotě okolo 850 K, kdy mizí anomálie piezo-optického koeficientu. Současně minima v rozmezí 655-695 K mění závislost na trvání ?thermoannealing?, což vede k malému posunu teplot v minimech.
