Аннотация

The temperature dependence of the luminescence decay for a series of SDL YAG:Ce phosphors is investigated. Luminescence quenching excited by chip under heat-treatment is observed. The dependence of temperature on thermal luminescent intensity at elevated temperature (range from room temperature to 200°C) was tested. Noticeable luminescence quenching of SDL 2700 phosphor is observed at temperatures above 50°C, and by increasing temperature up to 200°C, the luminescence intensity decreases 5 times. Compare with sdl2700 phosphor, the temperature quenching of sdl3500 and sdl4000 phosphors is much lower. The investigated phosphors differ in the content of Gd3+. An explanation of the observed effects is proposed.
