摘要: Tetrapod-like ZnO (T-ZnO) nanostructures were synthesized by a simple vapor phase oxidation method without any catalysts or additives. We optimized the performances of T-ZnO adjusting partial pressure Zn vapour in total quartz chamber and obtained nanostructure materials high purity, uniform morphology size aspect ratio with low turn-on electric field 2.75 V μm(-1), large enhancement factor 3410 good emission stability for more than 70 hour continuous emission. Besides, based on T-ZnO, we developed metal grid mask-assisted water-based electrostatic spraying technology, fabricated large-scale, pollution-free, hole-shaped array cathode used triode structure planar light source. The controllable device intensively investigated results showed that uniformly illuminated luminous intensity as 8000 cd m(-2) under conditions 200 voltage 3300 anode voltage. research this paper will benefit development performance source nanostructures.
