Information × Registration Number 0207U002593, 0104U000586 , R & D reports Title The investigation of new nonlinear - optical and laser mediums in double borates systems of barium, strontium and lanthanums. popup.stage_title Head Oseledchik Yu.S., Registration Date 06-02-2007 Organization Zaporozhye State Engineer Academy popup.description2 As a result of performance of research work the phase structure of systems Sr - RE2O3 - B2O3 is established, the areas of the phase diagram crystallizazija of connections are established: Sr3RE (BO3) 3, Sr2O4, Sr4O7, Sr4B14O25, Sr6O10, REBO3, REB3O6 (RE = Pr, Nd); others are synthesized boratov of connection alkali ground and seldom groundof elements La2Ca10O19, La2Sr10O19, La2Ba10O19. The existing ways of synthesis and cultivation of crystals in threefold systems Вао - RE2O3 - B2O3 and Sr - RE2O3 - B2O3 are analysed, the differential -thermal and rentgeno-phase of the analysis receive the data for forecasting an opportunity of cultivation of monocrystals and development of technology their cultivation. The conditions of cultivation are investigated and samples of crystals Sr4O7, Sr6O10, Sr6O10:RE, Ва3RE (BO3) 3, Sr3RE (BO3) 3, RЕВО3, RЕВ3O6 (RE = Pr, Nd) are received. The literary data on structural features, physical properties and prospect of use of crystals boratov seldom ground of elements andcrystals double boratov alkali ground and seldom groundof elements are analysed. The test researches of optical and linear-optical properties of the received crystals are carried out(spent). Is investigated termostimulirovanaj luminescence of radiating defects ozarennuh of glasses, polycrystals and monocrystals tetraborata strontium. The system of registration of weak light signals by a method to the account photon is developed. The results can be used in scientific researches and laser instrument making.
