Abstract

Tb³⁺/Yb³⁺ codoped Na₅Lu₉F₃₂ single crystals with near-infrared (NIR) emission are achieved by an improved Bridgman approach. Energy transfer from Tb³⁺ to Yb³⁺ ions is affirmed by the photoluminescence (PL) emission spectra and decay curves characterization. On the basis of the analysis of energy transfer rate dependence on the Yb³⁺ concentration, the interaction between Tb³⁺ and Yb³⁺ ions in Na₅Lu₉F₃₂ single crystals is confirmed through the one-to-one energy transfer process. Results demonstrate that the prepared Na₅Lu₉F₃₂ single crystals might be promising candidates to convert sunlight to improve the performance of the silicon solar cells.
