Abstract

Very intense green and red emission was observed at room temperature from the ⁴S_3/2 and ⁴F_9/2 levels of Er³⁺:Y₂O₃. A cw diode laser at 975 nm was used as a pump for resonant sequential excitation of the ⁴I_11/2 and ⁴F_7/2 levels. The fluorescence was easily visible to the naked eye, even with 27 mW of excitation power. It was found that at 850 mW of cw excitation power the total luminance was 39,000 cd/m². This corresponds to ∼100 μW of green emission and 270 μW of red emission.
