Time-resolved photoluminescence trpl spectra
WebThe emission mechanism in ZnS-capped 3-nm CuInS2 nanocrystals was studied by using time-resolved photoluminescence (TRPL). A typical TRPL spectrum demonstrates two broad emission bands. The spectral shifts as functions of the excitation power density and delay times from the excitation moment prove that both emission bands originate from … http://www.whxb.pku.edu.cn/EN/article/showBrowseTopList.do
Time-resolved photoluminescence trpl spectra
Did you know?
In a typical PL experiment, a semiconductor is excited with a light-source that provides photons with an energy larger than the bandgap energy. The incoming light excites a polarization that can be described with the semiconductor Bloch equations. Once the photons are absorbed, electrons and holes are formed with finite momenta in the conduction and valence bands, respectively. The excitations then undergo energy and momentum relaxation towards the band-gap minimum. Typ… WebTime Resolved Photoluminescence Spectroscopy (TRPL) Time resolved photoluminescence spectroscopy probes those excited states which have a radiative …
