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 ...

Steady State Benchtop Spectrofluorometer from HORIBA Scientific. The FluoroMax-4 is the Most Sensitive Spectrofluorometer in a single bench-top unit for fluorescence spectroscopy
Steady state photoluminescence (PL) spectra at different excitation densities and the time-delayed PL response are studied in order to extract the nature of the radiative transitions in the material. It is shown that the 2 K PL response of Cu-rich layers is dominated by two donor–acceptor ...
