Glasses and glass-crystalline materials of compositions (in moles) 2Bi 2 O3; 3SiO 2 and 2Bi 2 O 3 ; 3GeO 2 were subjected to gamma radiation. The radiation doses were 10 5 and 10 6 rad. The ...
... on them in double and ternary systems. The intensification of research in the field of bismuth-containing borate systems has stimulated the creation of a number of new glass compositions that are distinguished ...
Glasses of compositions Bi 4 (Si x Ge 1-x ) 3 O 12 (x = 0.33; 0.5; 0.66, 1.00) and glass-crystalline materials based on them. The influence of the composition of the charge and the modes of heat ...
Glasses of compositions Bi 4 (Si x Ge 1-x ) 3 О 12 , where x = 0.33; 0.5; 0.66, cooking for 30 minutes and two-stage cooking. The values ??of their characteristic temperatures, densities, refractive ...
The formation of waveguides in the bulk of sintered nanoporous glass pre-impregnated in a bismuth nitrate solution was demonstrated. The influence of laser irradiation regimes on the refractive index change ...
The formation of microtracks in the volume of porous glass samples by femtosecond laser pulses which is of importance for laser writing of active optical waveguides was studied. It was found that impregnation ...
