The variations in the PL emission decay profiles are used as a probe to investigate the changes in the local environments of the rare-earth ions in the glass-ceramic waveguides.doi:10.1016/j.ceramint.2016.10.055Subhabrata GhoshSreeramulu Valligatla...
There, the excited state population decays exponentially with a time constant given by the radiative lifetime t0 of the excited state, and an outward- moving photon with the same temporal decay profile emerges in a spatial field mode corresponding to the atomic dipole transition21. Therefore, for...
4.3 Non-radiative Decay Channels TR spectroscopy, together with the temperature dependence of the integrated radiative intensity, can be used as sensitive probe of defect incorporation at the interfaces. In fact, from the PL decay time τL(T) and integrated radiative intensity IL(T) we can extra...
Minority carrier lifetime\(\tau \)is generally evaluated by using time-resolved photoluminescence (TRPL) in thin film semiconductors, such as Cu(In,Ga)Se2(CIGS)1,2,3,4,5, CdTe6or perovskite7,8,9,10. However, these photo luminescence (PL) decay times are influenced by surface recombination...
Furthermore, time-resolved PL measurements at the free exciton peak were carried out at room temperature. The decay profiles were of double-exponential form, and the decay time constants of 180 ps and 1.0 ns were obtained using a least-square fit of the data.Jung...
In addition, at a temperature the same decay profiles\nwere observed for the peak at 2.0 eV (620 nm) and 1.9, 1.8 eV, indicating that the photoluminescence\nof the specimen due to STE with single nature. Fig. 2 depicts the decay profiles at the peak around 2.0\neV at temperatures of ...
The emission decay profiles for thiol capped CdS nanocrystalline powders dispersed in DMF depend on the nature of the capping agents (thiols) used to passivate the CdS nanocrystallites. The time resolved PL studies show that the average values of PL lifetime are related to the size and size ...
It also serves as a necessary reference for the latter, a more advanced continuous modeling approach, which focuses on specific trajectories, but provides cellular flux parameter estimates for each single cell and thus directly connects single-cell transcriptomic profiles with tissue-scale cellular ...
From the results of time-resolved PL decay measurements, we find that there are two types of QDs exhibiting quite different PL decay profiles.doi:10.1016/S1386-9477(99)00345-8K MatsudaT MatsumotoH SaitoK NishiT SaikiElsevier B.V.Physica E: Low-dimensional Systems and Nanostructures...
time-resolved spectroscopy propertiesphotoluminescence propertiesThe PL properties of Gd(BO2)3 and Gd(BO2)3 activated with Eu3+ are investigated. The energy transfer phenomenon from Gd3+ to Eu3+ ions can be drawn from the spectra. Concentration quenching phenomenon does not happen. The decay ...
