Characterization of cuprous oxide thin films on n-Si substrate prepared by sol-gel spin coating
Dewi Suriyani, Che Halin, Dr.; Ibrahim, Abu Talib, Prof. Dr.; Muhammad Azmi, Abd Hamid; Abdul Razak, Daud (MASS Malaysia, 2008)Cuprous oxide films were successfully grown onto a n-Si substrate with (100) orientation via sol-gel spin-coating method at room temperature in air followed by annealing in 5% H2 + 95% N2 atmosphere. The annealed temperatures ... -
The effect of spin coating rate on morphology and optical properties of cuprous oxide thin film prepared by sol-gel technique
Dewi Suriyani, Che Halin, Dr.; Ibrahim, Abu Talib, Prof. Dr.; Abdul Razak, Daud; Muhammad Azmi, Abd Hamid (Australian Ceramic Society, 2010)Cuprous oxide thin films were successfully grown on indium tin oxide (ITO) coated glass by sol-gel spin coating using diethanolamine (DEA) as a solubility agent. The films were annealed at 350 °C in 5% H2 + 95% N 2 atmosphere. ... -

Overview of pathogenic micro-organisms destruction in contaminated water by oxide photocatalysis
Noor Azira, Mohd Noor; Muhammad Asri, Idris, Dr.; Dewi Suriyani, Che Halin, Dr.; Mohd Nazree, Derman, Dr.; Mohd Arif Anuar, Mohd Salleh (Trans Tech Publications, 2013)The titanium dioxide (TiO2) is a semiconductor oxide photocatalys, which is chemically and biologically inert but exhibits excellent photolytic activity in the ultraviolet (UV) region. Progress in photocatalytic water ... -
Physical properties of cuprous oxide thin films grown on n-Si substrate by sol-gel spin coating
Dewi Suriyani, Che Halin, Dr.; Ibrahim, Abu Talib, Prof. Dr.; Abdul Razak, Daud; Muhammad Azmi, Abd Hamid (Penerbit Universiti Kebangsaan Malaysia (UKM), 2009)Cu2O films were grown on n-Si substrates via the sol-gel spin-coating method. 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 ... -
