The aim of this project is to develop and characterize nanostructured rare earth doped oxyfluoride glass ceramic materials tailored for highly efficient luminescence performance. In order to achieve the desired luminous properties such as high colour rendering index and quantum yield values of the emission as well as the repeatability required for practical applications it is planned employ structure sensitive X-ray diffraction and electron microscopy characterization techniques. State of art optical and magnetic resonance spectroscopy investigations at cryogenic temperatures are planned to determine the correlation of optical properties with activator local structure. The scientific novelty of this project is the emphasis on quantitative characterization of the studied materials which will advance the applicability of transparent glass ceramics for industrial use. The obtained results will be published in at least 3 articles in international journals with SNIP>1, one patent application and will serve as a foundation for future applied science project calls, including the EU Horizon program. The scope of this project contributes to Latvia’s priority direction in science “Technologies, materials and systems engineering for increased added value products and processes, and cybersecurity” and will advance the knowledge base in the smart specialization area of “Smart materials, technology and engineering systems” increasing the competitiveness of Latvian scientists in the world.
