Project description:
Materials with self-sustained emission in the ultraviolet (UV) spectral range present significant potential in science, industry, and everyday life. The scientific objective of the project is to develop efficient UV-persistent phosphors based on biocompatible phosphate materials to assess their viability for practical applications. Planned actions will include the synthesis and characterisation of pyrophosphate materials, advanced spectroscopic analysis of UV persistent luminescence mechanisms, and defect engineering to improve luminescence efficiency. The novel results, published as at least four scientific articles in Q1/Q2 journals, are expected to advance the knowledge base on point defects, charge transfer and luminescence processes in phosphate materials. The quantitative assessment of key performance parameters will enable the evaluation of the developed materials for practical applications. This research project will contribute to the Smart Specialisation Strategy (RIS3) area “smart materials, technologies and engineering systems”, by developing efficient optical materials and advancing novel products via future applied project calls.
