The films were annealed under 5% H2 + 95% N2 atmosphere at 350°C, 450°C and 550°C. Diffractogram obtained by the grazing angle x-ray diffractometry showed that the crystallinity of the films increased with increasing annealing temperature. Scanning electron microscopy micrographs revealed that the Cu2O films contain grains of irregular size indicating that the film growth followed the Volmer-Weber growth mode. The micrographs showed the size evolved from irregular shapes with average size of 100 nm at 350°C into rectangular shapes with average size of 200 nm at 550°C. Optical reflectance for 450°C and 550°C film increased gradually at wavelength 480 nm. Higher reflectance for the 450 °C film might be due to better coverage of the film. It also showed that optical absorption occured at wavelength below 480 nm. 2014-06-16T04:18:36Z 2014-06-16T04:18:36Z 2009 Article Sains Malaysiana, vol. 38(2), 2009, pages 215-218 0126-6039 http://www.ukm.my/jsm/english_journals/vol38num2_2009/vol38num2_09page215-218.html http://dspace.unimap.edu.my:80/dspace/handle/123456789/35560 en Penerbit Universiti Kebangsaan Malaysia (UKM)
