Energy transfer and luminescent properties of Ce3+, Cr3+ co-doped Y3Al5O12

► Ce3+-Cr3+ co-doped Y3Al5O12 can absorb UV/visible light and give far-red emission. ► Energy transfer from Ce3+ to Cr3+ occurs with efficiency ∼0.8. ► The studied material may be used to improve the efficiency of Si solar cell.
