摘要: Abstract Polycrystalline ZnO thin films have been grown on Si (1 0 0) substrate using filtered cathodic vacuum arc technique. Room temperature photoluminescence reveals a strong near-band edge emission at 378 nm and weak green around 510 nm from the film deposited 230°C. The intensity ratio of to is about 100 indicating high quality film. An additional 420 nm, corresponding interstitial oxygen level, also observed 430°C. were characterized by X-ray diffraction, photoelectron spectroscopy, Raman as well transmittance measurement.
