摘要:
A phosphor thin film (3a) of a compound of zinc, cadmium, manganese or alkaline earth metals and an element of group VI is sandwiched by barrier layers (2a,2b) having a larger energy gap than that of the phosphor thin film, and a plurality of the sandwich structures are accumulated thicknesswise to constitute a light-emitting device. The phosphor thin film ensures the confinement of injected electrons and holes within the phosphor thin film. The light-emitting device has a high brightness and a high efficiency.

锌,镉,锰或碱土金属的化合物的荧光体薄膜(3a)和VI族的元素被具有比荧光体薄膜的能隙更大的能隙的阻挡层(2a,2b)夹持, 多个夹层结构被厚度累积以构成发光装置。 荧光体薄膜确保了荧光体薄膜内注入的电子和空穴的限制。 发光装置具有高亮度和高效率。
