Very intense green and red emission was observed at room temperature from the 4S3/2 and 4F9/2 levels of Er3+:Y2O3. A cw diode laser at 975 nm was used as a pump for resonant sequential excitation of the 4I11/2 and 4F7/2 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.
