Cooperation of the Physico-Technical Institute and the Kola Science Center of the Russian Academy of Sciences

Post-graduate student at the Institute of Chemistry and Technology of Rare Elements and Mineral Raw Materials of the Kola Scientific Center of the Russian Academy of Sciences is engaged in research activities in the educational and scientific laboratory of spectroscopy at PetrSU.
Experimental studies of the optical properties of lithium niobate crystals have been organized in the educational and scientific laboratory of spectroscopy of the Physico-Technical Institute.

This is a joint work with the Institute of Chemistry and Technology of Rare Elements and Mineral Raw Materials of the Kola Scientific Center of the Russian Academy of Sciences. Nonlinear optical lithium niobate crystals are a promising functional material for integrated optics, laser technology, and optoelectronics. The laboratory has a modern spectrograph with a sensitive CCD detector, with the possibility of heating or cooling samples up to 15 K, on ​​which the photoluminescent activity of crystals in the visible and infrared regions of the spectrum is studied. Luminescence analysis makes it possible to judge the presence of defects of various nature and can serve as a criterion for evaluating the quality of a crystal.

The research is carried out by a graduate of PetrSU, post-graduate student of IKhTREMS M.V. Smirnov. The work is carried out within the framework of the RFBR grant “Regularities of the formation of a defect structure, luminescent and photorefractive properties of ceramics and single crystals of lithium niobate single and double doping with zinc and magnesium, obtained by different technologies, depending on the concentration of alloying elements.”
