Abstract

The green up-conversion (UC) behavior was observed in a new phosphor Y 6W 2O 15:Er 3+. Taking the concentration quenching and sensitization effect into consideration, we obtained the optimized phosphor Y 5.86W 2O 15:0.05Yb 3+,0.09Er 3+. With the adhesion of Y 5.86W 2O 15:0.05Yb 3+,0.09Er 3+ phosphor layer, the spectral response was first observed in a 973-nm laser-driven GaAs solar cell. A maximum output power of 0.339 μW was measured using a 300-μm UC phosphor layer on illumination with a 973-nm laser at 145.65 W/cm 2. These results verified the UC effect of the Y 5.86W 2O 15:0.05Yb 3+,0.09Er 3+ phosphor synthesized herein.
