Theoretical modelling of the frequency-dependent phase shift between emission and excitation in ZnO nanorod photoluminescence spectra
Original language description
Hydrothermally growth, zinc oxide (ZnO) nanocrystals are known for their interesting scintillation and photocatalytic properties. In our previous paper we presented an optical setup for measuring spectrally resolved photoluminescence (PL) mean decay time using conventional UVLED with sinusoidal excitation and a phase shift method with about 10 ns time resolution, recently upgraded to 1 ns. Photoluminescence decay is the process by which the excited state of a material, induced by the absorption of photons, returns to the ground state, emitting light in the process. This process can be measured in time domain, with the decay rate indicating how quickly the material returns to its ground state after excitation, or equivalently in frequency domain, with the difference between the phase of the light wave at the moment of excitation and the phase of the light wave at the moment of emission. Here we report on the theoretical modelling of the frequency-dependent phase shift between emission and excitation in photoluminescence spectra of ZnO nanorods.
