Conference 3 – 5th International Workshop on Functional Nanostructured Materials – “FuNaM-5”

The 5^th International Workshop on Functional Nanostructured Materials (FuNaM-5) is a scientific meeting focused on recent advances in the synthesis, characterization, and applications of functional nanostructured materials. The workshop provides a platform for researchers to exchange ideas and discuss new trends in nanoscience, including topics such as photonic, catalytic, electronic, and energy-related nanomaterials. FuNaM-5 aims to foster interdisciplinary collaboration between materials scientists, chemists, and physicists, promoting the development of innovative nanostructures for advanced technological applications

Abstract: Developing efficient Er³⁺,Yb³⁺:YAG eye-safe lasers is a priority of modern laser technology. The increase in the lasing efficiency of the Er³⁺,Yb³⁺:YAG materials is possible by increasing the efficiency of energy transfer from Yb³⁺ ions to Er³⁺ ones. The efficiency of energy transfer depends on a number of parameters, the most important of which is the distance between energy donors and acceptors. The distance between the Yb³⁺ and Er³⁺ ions can be modified through the change in the concentrations of these ions. Therefore, the development of efficient Er³⁺,Yb³⁺:YAG materials is possible by tuning the concentrations of both Er³⁺ and Yb³⁺ ions . his work focuses on the influence of the concentration of Yb³⁺ ions on the spectroscopic properties of Er³⁺,Yb³⁺:YAG transparent ceramics. Concentration series of Er³⁺,Yb³⁺:YAG transparent ceramics were synthesized by solid-state sintering in vacuum. The concentration of the Er³⁺ ions were the same for all the samples and equal to 0.5 at%, while the concentration of Yb³⁺ ions was 0 at%, 5 at%, 10 at%, and 20 at%.
