Novel transparent nanocomposite oxyfluoride materials for optical applications
Workshop of ISSP UL’s Doctoral School “Novel transparent nanocomposite oxyfluoride materials for optical applications". Seminar led by U. Rogulis, coordinator of LZP 2018/1-0335 grant.
About the workshop
The aim of this project is to develop and characterize nanostructured rare earth doped oxyfluoride glass ceramic materials tailored for highly efficient luminescence performance. 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.
Results (09/2018-08/2021):
5 scientific publications including 2 Open Access; 1 chapter of a book, 1 publication in popular science magazine Ilustrētā Zinātne; participation in 6 international conferences with reports; 1 Latvian patent application.
During the workshop, the participants will be acquainted with the scientific results obtained during the course of the project:
- An overview of the literature on studies of oxyfluoride glass-ceramics using electron paramagnetic resonance spectroscopy.
- Synthesis of new samples of oxyfluoride glass-ceramics.
- A new method for quantitative analysis of rare earth activator distribution in glass-ceramic nanocomposite materials.
- First time of synthesis of glass ceramics containing the crystalline phase of hexagonal NaErF4.
- Chromium ion incorporation in lanthanum oxychloride using magnetic resonance (EPR, ENDOR) and X-ray spectroscopy (XPS, XANES) methods.
- The applicability of the EPR method for the characterization of Er3+ ions in glasses and glass-ceramics.
