The applications of ZnO nanorods in poly [2-methoxy-5-(2-ethyl-hexyloxy)-1, 4-phenylene vinylene]solid state cathodoluminescence device
ZnO纳米棒在聚[2-甲氧基-5-(2-乙基-己氧基)-1,4-苯撑乙烯撑]固态阴极射线发光器件中的应用研究

A solid state cathodoluminescence (SSCL) device in which ZnO nanorods act as the field emission electrode and SiO2 as the electronic accelerating layer and poly 2-methoxy-5-(2-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) polymer as the luminescent layer is first designed. Under AC bias,SSCL of MEH-PPV is realized. The luminescence peaks are located at 580 nm and 450 nm,respectively. Compared with the device without the accelerating layer,we find that mixed-excited mode device can achieve greater brigh...
