为了寻求提高场致发光屏发光亮度的方法,不仅可以沿着改进合成场致发光体途径的方向来进行,而且也可以采用发光体镀层的新方法来实现。电泳法是具有前途的镀层制备法之一。其优点在于:在衬底上形成的镀层具有很高的颗粒密度和颗粒的均匀分布。这就使得场致发光屏的亮度有所提高。目前用喷雾法制备的场致发光屏,密度低,厚度分散性很大(10—15％),因而发光亮度也不均匀。 许多工作表明,应用电泳法制作场致发光屏原则上的可能性。但是,具体尚未推广到工业上去广泛采用。 本工作讨论从悬浮液中电泳沉积场致发光体过程的研究结果,及其在电场中的行为,籍以研究形成场致发光屏的基本规律性。作为研究的对象,我们曾选用ЭЛ—515、ЭЛ—510M、ЭЛ—580M、ЭЛ—650、ЭЛ—455标号的场致发光体。
In order to seek ways to improve the luminosity of electroluminescent panels, not only can it be done in the direction of improving the way of synthesizing electroluminescent emitters, but also a new method of luminescent material plating can be adopted. Electrophoresis is one of the most promising coating preparation methods. The advantage is that the coating formed on the substrate has a very high particle density and a uniform distribution of particles. This makes the electroluminescent screen brightness has increased. At present, the electroluminescent screen prepared by the spray method has low density and great thickness dispersion (10-15%), so the luminescent brightness is also not uniform. Many work shows that the possibility of producing electroluminescent screens by electrophoresis is, in principle, possible. However, it has not been widely adopted in industry yet. This work discusses the results of the electrophoretic deposition of electroluminescent devices from suspensions and their behavior in electric fields to study the basic regularity of forming electroluminescent screens. As the object of study, we have selected ЭЛ-515, ЭЛ-510M, ЭЛ-580M, ЭЛ-650, ЭЛ-455 labeled electroluminescent.
