    • 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. ...
    • Green synthesis of silver nanoparticles using local honey 

      Haiza, Haroon; Azizan, Aziz, Assoc. Prof. Dr.; Aizat Hazwan, Mohidin; Dewi Suriyani, Che Halin, Dr. (Trans Tech Publications, 2013-05)
      In this work, silver nanoparticles have been successfully prepared with a simple, cost-effective and reproducible aqueous room temperature green synthesis method. Honey was chosen as the eco-friendly reducing and stabilizing ...
    • Mechanism of current transport for a photoelectrochemical cells of ITO/Cu2O/PVC-LiClO4/graphite 

      Dewi Suriyani, Che Halin, Dr.; Haiza, Haroon; Ibrahim, Abu Talib, Prof. Dr.; Abdul Razak, Daud, Prof. Dr.; Muhammad Azmi, Abd Hamid, Assoc. Prof. Dr. (Trans Tech Publications, 2013)
      This paper deals with the current transport mechanism of solid state photoelectrochemical cells of ITO/Cu2O/PVC-LiClO4/graphite as well as the physical properties of a component of a device affecting its performance. The ...
    • 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 ...
