概要
- 論文の詳細を見る
Cathodoluminescence of BaF_2 and CsCl has been studied at room temperature by changing the applied acceleration voltage from 2 to 15 kV. A two-photon emission process takes place in these materials. One is an ordinary interband luminescence(IBL)between the conduction and valence bands. The other is a specific type of luminescence, the so-called Auger-free luminescence(AFL), between the valence and outermost-core bands. It is found that the intensity of AFL enhances with increasing acceleration voltage, compared to that of the IBL. The present result is important and useful for improving the quantum yield of light-emitting devices.
