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+:2F5/22F7/2) emission was achieved under the excitation of the Eu3+:5D3 energy level at 405 nm. Through the lifetime Eu3+:@616 (λexc=394 nm) measurement, the maximum of effective quantum efficiency (ηEQE) 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.
