The main methods for obtaining gradient optical elements are presented, among which ion-exchange diffusion occupies the dominant place. A new method for obtaining gradient optical media, based on the discovery ...
... microstructure and optical properties of YSAG:Nd3+/YSAG:Sm3+ composite ceramics was also investigated. It is shown that at the interface between the YSAG:Nd and YSAG:Sm layers there is a region of gradient ...
Methods of laser micro- and nanomodification structure of transparent dielectrics open promising prospects for the creation of a new type glass-crystalline materials and new applications. In this work, ...
A method for obtaining high-purity tungsten (VI) oxide based on two-stage sublimation purification has been developed. An impurity analysis of commercial preparations of tungsten (VI) oxide by inductively ...
An increase in glass strength can be achieved by modifying the surface layer. Considered: gradient glasses, in which the strength of the glass increases due to the difference in TCLE over the thickness ...
