Visible photoluminescence from ZnO/diamond-like carbon thin films

ZnO/diamond-like carbon （DLC） thin films are deposited by pulsed laser deposition （PLD） on Si （111） wafer. Visible room-temperature photoluminescence （PL） is observed from ZnO/DLC thin films by fluorescence spectrophotometer. The Gaussian curve fitting of PL spectra reveals that the broadband visibl...

More Information
Summary:ZnO/diamond-like carbon （DLC） thin films are deposited by pulsed laser deposition （PLD） on Si （111） wafer. Visible room-temperature photoluminescence （PL） is observed from ZnO/DLC thin films by fluorescence spectrophotometer. The Gaussian curve fitting of PL spectra reveals that the broadband visible emission contains three components with λ=508 nm, 554 nm and 698 nm. The origin and possible mechanism of the visible PL are discussed, and they can be attributed to the PL recombination of ZnO and DLC thin films.
