Research Laboratory for Optical Ceramics Materials

Main research areas:

Development of scientific and technological principles for obtaining new polycrystalline laser materials with anisotropic structure based on strontium fluorapatite and rare-earth elements

Research objectives:

Development of methods for synthesis of FAP, S-FAP, Y2O3 powders satisfying the requirements in terms of  morphology, chemical and phase purity for laser ceramics sintering. Investigation of microstructure formation of FAP, S-FAP, Y2O3 ceramics during consolidation of nanopowders by hot pressing.

Key results:

2021
- The Laboratory for Optical Ceramic Materials was established, laboratory equipment and reagents for its work were procured

2022

- The methods for synthesis of highly dispersed strontium fluorapatite (SFAP) powders, including those alloyed with tullium, holmium and erbium ions, have been developed; the conditions for sintering dense ceramics with an average grain size of 100 nm using SFAP have been determined
- Luminescent properties of Tm, Ho, Er:SFAP ceramics have been studied, and their application in manufacturing laser media in the range of 2-3 microns (for ecological and medical applications) has been shown to have good prospects.
- The Russian Science Foundation project "Laser nanoceramics based on MgO-RE2O3 composite materials alloyed with Tm, Ho, and Er ions" has received support.
