The steady-state photoluminescence (PL) spectra of AgInSe 2 grown by the Hot-Press method have been examined. The broad peaks located at 1.19eV and 1.16eV are very likely to be the donor–acceptor-pair emissions. The energies of the donor levels participating in these emissions correspondingly...
A systematic investigation has been made on steady‐state and time‐resolved photoluminescence (PL) in microcrystalline silicon (μc‐Si) at liquid‐helium temperature. The steady‐state PL spectra on various grain sizes and volume fractions are examined. It is found that the low‐energy emission ...
We report steady-state and time-resolved photoluminescence (TRPL) measurements on individual GaN nanowires (6–20μmin length, 30–940 nm in diameter) grown by a nitrogen-plasma-assisted, catalyst-free molecular-beam epitaxy on Si(111) and dispersed onto fused quartz substrates. Induced tensile ...

What is Photoluminescence Spectroscopy Photoluminescence spectroscopy, often referred to as PL, is when light energy, or photons, stimulate the emission of a photon from any matter. mehr anzeigen 1 2 Produktaccessoires Absorption Accessory Auto Titration Injector F-3005 and F-3006 ...
Time-resolved photoluminescence mapping (spatially and spectrally resolved) of InGaN/GaN MQW structures revealed bright and dark spots with nearly constant peak energy and time decay. The results suggest that the bright and dark spots of the samples correspond to islands with higher and lower ...

We investigated differences between the transient state and steady state exciton–exciton annihilation rates based on Frster-type energy transfer. The exciton–exciton annihilation rate of an organic semiconductor is usually determined by transient state photoluminescence measurements using a pulsed laser or...
