The nano-diamond film has excellent field emission performance, and its field emission intensity is much higher. This is due to the fact that the nano-diamond film has a smaller grain size, a lower threshold voltage, and it is easy to emit electrons from the film. The cold cathode field emission performance of the nano-diamond film is far superior to that of the micro-diamond film. It is not only efficient but also can greatly reduce the production cost and energy consumption when used as a field emission device. Taken together, nanodiamond films have the potential to become an important material for the preparation of next-generation flat-panel displays.

Studies show that diamond nano film can achieve high self-transmittance from ultraviolet to infrared bands, and has anti-fog and underwater self-transmission properties.

Currently, the super-thin film with nano diamond with wide band and  excellent light transmittance can be used on various commercial substrate materials and have good application prospects in various fields.
