Zn/Sn共掺杂MgO功能层对AC PDP放电性能的影响

采用化学共沉淀法制备出Zn/Sn共掺杂MgO纳米粉末,利用旋涂法将其涂覆在等离子体显示器（AC PDP）的前基板上作为功能层,以改善AC PDP的放电性能。X射线衍射（XRD）、光电子能谱（XPS）和扫描式电子显微镜（SEM）的分析结果表明,Zn和Sn原子被成功掺入MgO晶格中。紫外-可见分光光度计的测试结果显示,Zn/Sn共掺杂MgO功能层的加入使基板的可见光透过率降低了4%~7%。在200~450 torr、7% Xe+Ne的放电条件下,与传统AC PDP相比,新型功能层的加入有效降低了AC PDP的着火电压和维持电压。因此,该功能层对于提高AC PDP的放电效率和降低其功耗具有重要意义。

Effects of Zn- and Sn-Doped MgO Powdered Functional Layer on Discharge Characteristics in AC Plasma Display Panels

Zn- and Sn-doped MgO powder preparing via a chemical coprecipitation method was spin-coated on alternating current plasma display panel (AC PDP) front panel as a functional layer to improve the discharging performance of AC PDP. The new products were characterized by X-ray diffraction (XRD), X-ray photoelectrom spectroscopy (XPS), scanning electron microscope (SEM) and an ultraviolet-visible spectrophotometer. The results showed that zinc and tin atoms had been successfully incorporated into the crystal lattice of MgO, which made the transmission only decrease by 4%~7%. Within 7% Xe-Ne pressure range of 200~450 torr, the new functional layer consistently showed lower firing and sustain maximum voltages than that of the conventional MgO layer. Therefore, this functional layer was important for improving the discharge efficiency of AC PDP and reducing its power consumption.
