AbstractStimulated emission from single ZnO tetrapod nanowires was studied by time-resolved photoluminescence (TRPL) spectroscopy. The samples were excited by a 300 fs pulse and the emission spectra collected as a function of time. The spectra exhibit a change in the position and the shape of the emission peak with time. The time evolution of the emission spectra was studied for different pump excitation fluences. The spectra exhibited a blue shift with increasing pump fluence, while for all pump fluences a red shift of the peaks with time was obtained. Possible reasons for the observed behaviour are discussed.
