主 题：spectroscopy coating Titanium
摘 要：An electrophoresis solution,prepared in a specific ratio of titanium (Ti)-doped nano-diamond,is dispersed by ultrasound and the nano-diamond coating is then deposited on a polished Ti substrate by *** high^-temperature vacuum annealing,the appearance of the surface and the microstructures of the coating are observed by a metallomicroscope,scanning electron microscopy and Raman *** field emission characteristics and luminescence features are also tested,and the mechanism of the field emission characteristics of the Ti-doped nano-diamond is *** experimental results show that under the same conditions,the diamond-coated surface (by deposition) is more uniform after doping with 5 mg of Ti *** with the undoped nano-diamond cathode,the turn-on fields decline from 6.95 to 5.95 V/μ*** the electric field strength is 13.80 V/μm,the field emission current density increases to 130.00 μA/cm^(2).Under the applied fields,the emission current is stable and the luminescence is at its best,while the field emission characteristics of the 10 mg Ti-doped coating become worse,as does the *** reason for this could be that an excessive amount of TiC is generated on the surface of the coating.
