Zn 0.8 Na 0.1 Co 0.1 O thin films were prepared by the pulsed laser deposition(PLD) on SiO 2 substrates at different substrate temperatures(400 ℃,500 ℃,600 ℃).The Xray diffraction(XRD),the atomic force microscopy(AFM),the fluorescence spectrometer and the four-probe tester were applied to characterize the structure,optical and electrical properties of the films,respectively.The effects of substrate temperature on the structure,optical and electrical properties of Zn 0.8 Na 0.1 Co 0.1 O thin film...
