C-ZnSe:Ga的室温蓝色注入式发光

本文首次报导了C-ZnSe:Ga的室温蓝色注入式发光,测量了有关特性并讨论了发光机理.电致发光光谱具有强的4800A的蓝峰和弱的6300A的红峰.随着正向电压的增加,6300A的自激活发射相对减弱,而4800A的蓝色边缘发射逐渐增强.因此,当电压增加时,发光颜色由红色经黄色和绿色,逐渐变成纯蓝色.在明亮的房间里可以观察到鲜明的蓝色发射.文末提出了ZrSe多色显示的设想.

BLUE INJECTION ELECTROLUMINESCENCE OF C-ZnSe:Ga AT ROOM TEMPERATURE

The blue electroluminescence of C-ZnSe:Ga at room temperature is first reported,presented the measurement on the relative properties,and discussed the its luminous mechanism. A strong peak of the electroluminous spectra is at 4800A and a weak peak at 6300A. The self-activated emission at 6300A is reduced with increase of voltage,but the edge emission at 4800A increased. Therefore, the colours vary from red via yellow and green to blue.The bright blue light is observed in the bright room. Finally,the tentative idea of ZnSe varicoloured display is presented.
