Photoconductivity of MEH-PPV/TiO2 nanocomposite thin films / Fazlinashatul Suhaidah Zahid

This paper investigates the photoconductivity of the MEH-PPV/TiO2 nanocomposite thin films by varying the weight ratio of TiO2 and was deposited on the glass substrates by using spin coating technique. The influence of the amount of TiO2 in the nanocomposite heterojunctions and photoconductivity as...
