摘要：
Thin films of zinc oxide (ZnO) with ammonia solution to 300m1 of aqueous solution Zn(NO3)2 center dot 6H(2)O (0.3M) are created via (CBD) technique on commercial glass substrates with bath temperature (80 +/- 5) degrees C and annealing temperatures at (373, 473 and 573)K at constant time of lh. The deposited films optical absorbance was defined utilizing SP3000NANO optima (UV-V is spectrophotometer) and shows that the optical energies gaps for ZnO films increase slightly through a rise in temperature of annealing of the samples at 373K and 473K and register around 3.77eV and 3.78eV respectively. While the energy gap decreases to 3.73eV with increase the annealing temperature at 573K. The wide band gap ZnO has applications of wide array in areas include solar cells, light conductors, chemical sensors and ultraviolet laser diodes.
