Film preparation conditions and characterization of co-deposited tungsten doped zinc oxide phosphor

Need for efficient blue light emitting source for optoelectronic device applications such as flat panel displays has made the research in luminescent material ever so important. Tungsten doped zinc oxide (ZnO:W) has been identified as a blue light emitting phosphor exhibiting cathodoluminescence near 490 nm. This paper details work done on ZnO:W phosphor preparation conditions for efficient tight emission from the phosphor. Material characterization to identify the possible source of blue light emission will also be discussed.
