Luminescent of nano-diamond field emission

In this paper, the low-cost sol-gel method was adopted to prepare transparent uniform Nano-diamond films on large areas of ITO glass. The mixture of Nano-graphite and organic vehicles doped to nano-diamond paste. After fabricating paste, the Nano-diamond was further ultrasonic dispersed. Through test a variety different content proportion of Nano-diamond paste, the best suitable paste proportion was found. Nano-diamond film was prepared by sol-gel method at 3000/min. The samples of Nano-diamond transparent film were micro-analyzed and tested the field emission characteristics.
