Abstract

A single ZnO micro ribbon was characterized by time-resolved photoluminescence (TRPL) spectroscopy. It was found that different laser incidence positions and sample locations exhibit different luminescence emissions. The density of photons exciting the sample plays a key role on these observations. Depending on the position (location), light can spread out or can be confined resulting to low or high excitation intensities, respectively. The results indirectly show an intensity dependence TRPL experiment without doing an actual one on micro/nano structured samples.
