摘要: The present invention provides a solid state light-emissive display apparatus of high brightness and efficiency, high reliability, and of thin type, and method of manufacturing the same at low cost.
Said apparatus has the luminous thin film made up by laminating or mixing crystal fine particle coated with insulator (5) of nm size and fluorescent fine particles (7) of nm size, and the lower electrode and the transparent upper electrode sandwiching said luminous thin film, wherein the electrons injected from said lower electrode are accelerated in the crystal fine particle coated with insulator layer (6) not being scattered by phonons to become high energy ballistic electrons, and form excitons (13) by colliding excitation of fluorescent fine particles. Since said fluorescent fine particles are of nm size, the exciton concentration is high, and luminescence intensity by extinction of excitons is also high.摘要翻译: 本发明提供一种高亮度,高效率,高可靠性,薄型的固态发光显示装置及其制造方法。 所述装置具有通过层叠或混合涂覆有nm尺寸的绝缘体(5)和nm尺寸的荧光细颗粒(7)的晶体细颗粒和下电极和透明上电极夹层而制成的发光薄膜 所述发光薄膜,其中从所述下电极注入的电子在涂覆有不被声子散射的绝缘体层(6)的晶体细颗粒中加速成为高能弹道电子,并通过碰撞荧光的激发形成激子(13) 细颗粒。 由于所述荧光细粒子的nm大小,因此激子浓度高,激子的消光发光强度也高。
