In this paper, nanodiamond films (NDF) were prepared on glass substrate by screen printing with nanodiamond. The NDF was printed with two layers and treated with different surface treatments.The field emission model of nanodiamond thin film was established. Field Emission of different Ratio was studyed. The mechanism by which the field emission characteristics of nanocrystalline diamond films are improved was analyzed.

Steel Substrates

Silver thin film of 5 nm thicknesses was evaporated on glass and stainless steel substrates and annealed at 300°C for one hour. Then these samples were characterized by using X-ray diffraction method (XRD), Scanning Electron Microscopy (SEM), UV-VIS spectroscopy, and subjected to anti-microbial resistance test. XRD analysis showed as deposited silver thin film coated on glass substrate and stainless steel substrates have amorphous nature. The annealed Ag thin film coated on glass and stainless steel substrates showed crystallinity with silver phase and their crystalline size were in the range of 30-40 nm and 17 nm respectively. SEM image indicates that formation of silver nanoparticles with spherical morphology after annealing on the glass substrate. But there is no nanoparticles formation was observed on annealed steel substrates. The anti microbial resistance test was done against E.Coli and that microbial growth was observed after 24 and 48 hrs. The results displayed a microbial resistance after 24 hrs for annealed Ag thin film coated on glass substrate due the formation of silver nanoparticles.
