Abstract

In the paper spectroscopic properties of aluminosilicate glasses co-doped with Eu³⁺/Yb³⁺ have been investigated. Optimization of rare-earth content has been performed by co-doping glass with xEu₂O₃–yYb₂O₃, x = 0.25, y = 0, 0.50, 0.75, 1, 1.25, 1.5 (mol %). Quantum cutting at 950-1100 nm (Yb³⁺:²F_5/2→²F_7/2) emission was achieved under the excitation of the Eu³⁺:⁵D₃ energy level at 405 nm. Through the lifetime Eu³⁺:@616 (λ_exc=394 nm) measurement, the maximum of effective quantum efficiency (η_EQE) were determined as 136.5 % for glass co-doped with 0.25Eu₂O₃/1.5Yb₂O₃ (mol %). The obtained results show possibility to applied developed glass as active converter layer which may improve efficiency of silicon solar cells.
