Luminescence of Doped Silver Chloride Crystals

概要

論文の詳細を見る
Luminescences of silver chloride crystals doped with CdCl_2 and FeCl_3 are measured spectroscopically at low temperatures. Effects of auxiliary infrared light on them and on photoconductivities are also measured. Cd ions change the normal luminescence of silver chloride of maximum at about 485 mμ to longer wavelength one of 545mμ at low temperatures. When the latter luminescence is thermally quenched, the usual maximum of 485 mμ recovers and then it is also thermally quenched. The iufrared light enhances the luminescence of 540mμ and quenched that of 485mμ. This quenching is drastic when Fe ions are added. The photoconductivity is enhanced by the infrared light in Cd doped crystals and almost not quenched in Fe doped crystals. An energy band model is given to explain the experimental results.
