Time-Resolved Photoluminescence Studies and Spectral Narrowing in ZnO Nanostructures

Pulsed-excitation photoluminescence studies of ZnO nanostructures show spectral narrowing and a corresponding decrease in lifetime with an increase in pump fluence. Results for structures grown on sapphire and silicon are presented.
