概要
- 論文の詳細を見る
A photoacoustic technique has been applied for studying light-induced darkening of Zn_xCd_<1-x>S: Ag, Al phosphors in various gas ambients. The threshold energy and the rate for the light-induced darkening depend on the bandgap energy of the materials. The darkening process occurs effectively in the mixed ambient gases of N_2, CO_2 and H_2O which are the components of air. A bleaching process has also been observed in a mixture of O_2 and H_2O.
