| Abstract | ||
| First,ZnO nanorod s were su ccessfu lly synthesized by simple evaporation method,u sing single stage controllable horizontaltu be fu rnace and qu artz tu be withou tcatalyst.The ZnO nano powd erwas mix ed with (10 and 20%)of TiO2 powd er(weightratio),then ZnO -TiO 2 thickfilms were synthesized u singsimple,low-cost efficient screen print techniqu e. The thick films were heated at 500 C ˚ for one hou rto remove the organic bind erand anyimpu rities.The prepared thickfilms were examined withX -Ray,and FESEM to stu d y the stru ctu raland morphology of the films,the X -ray results show that the films are polycrystalline with sharp and high intensity peaks indicating high crystalinity of the product.The FESEM pictures show nanorods with diameters less than 100 nm and several micrometers in length of ZnO withTiO 2 nanoparticles.ZnO -TiO 2 device was built up by electroding the thick films.The I-V characterization of the films were studied in dark and light,then photo detection parameters were estimated and it was found to be efficient and high response in UV range detection | ||
