Synthesis of RE-Ag,Al-RE-doped sol-gel glass and films for solar cells

摘要

The paper dealt with the study of fluorescence properties of sol-gel systems doped with rare-earth ions and co-doped with silver. The general problem for these types of inorganic phosphors was a very low absorbance in the visible range. Therefore, a sensitizer of lumi- nescence of the rare-earth ions should be selected and used. The sensitizer should possess a good absorbance in the visible range and strong interaction with the rare-earth ions. In this study silver ions were selected as the sensitizer.
