The steady-state photoluminescence (PL) spectra of perovskites on the FTO, PEDOT:PSS, or ZnCo2O4 were measured using a Princeton Instruments Acton 2150 spectrophotometer. A KIMMON KOHA He–Cd laser with double
. With increasing TCB content, the steady-state photoluminescence (PL) spectra reveal a reduced emission of theβ1phase at 816 nm, with a simultaneous increase of the emission of theαphase at 744 nm. From the PL spectra we determine that in pure CF theαphase concentration is negligibl...
The photoluminescence spectra of N+, Zn+ implanted GaAs1-xPx at 1.8–4.2KThe photoluminescent behavior of N + and Zn + implanted GaAs 1-xP x has been investigated at 1.8-4.2K. The experimental results show that the alloy composition x, at which the conversion of N-Zn transition N and ...
Photoluminescence spectra Fig. 4 presents the steady-state photoluminescence (PL) spectrum of [Ni(salophen)] obtained in DMSO (λexc = 378 nm; 1 × 10−5 mol L−1) with only one emission band at the blue-region centered at λPL = 420 nm with a Stokes Shift respecti...
Excitonic photoluminescence spectra in the ZnS-ZnSe strained-layer superlattices with imperfect heterointerfaces were studied experimentally. It is shown that the energy states of excitons in these structures are affected both by interface imperfections and internal strain caused by the lattice mismatch ...
state was still over 1.6 ms in the air (Fig.2h). Under vacuum conditions, the phosphorescent lifetime of the amorphous sample was as long as 0.23 s, being equal to the one of its crystals as shown in the photoluminescence (PL) intensity decay curves of Fig.2h. It means that ...
Additionally, the increased binding energy compared with that of TiO2 indicated an increased oxidation state (O2− to O−), which could enhance the photocatalytic oxidation of Hg0 [40]. Figure 7. XPS spectra of Ti 2p over TiO2, CuO/TiO2, CeO2/TiO2, and Bi2O3/TiO2. Figure 8. XPS...
describing a steady state PL experiment something sim- pler should suffice. The purpose of this paper is to attempt a physically motivated semi-empirical alternative that would allow for direct modelling of the experimental data in terms of small number of fitting parameters. We show that thi...

Employing time-resolved single-dot photoluminescence (PL) spectroscopy, the dynamics of charge and energy transfer within colloidal CdSeTe/ZnS quantum dots (QDs)/monolayer molybdenum disulfide (MoS2) heterostructures were examined. A time-gated approach is used to segregate the photoluminescence (PL) ...
