ZnO filmsPhotoluminescenceAdsorption of oxygenWe studied the photoluminescence (PL) spectra in the near-band-edge region of undoped ZnO films as a function of temperature to determine the thermal quenching behavior in the emission intensity. The quenching of the PL intensity was found to change to ...

We report, for the first time, on the strain related features of the near band-edge luminescence of ZnS epilayers and find emissions that can be related to both heavy-hole (hh) and light-hole (lh) character. Layers with different relative strain show well resolved peaks due to the recombin...
摘要: Near-band edge photoluminescence in CuGaS<SUB>2</SUB> has been measured at room temperature. It has been found that the green emission at 2.454 eV is strongly polarized parallel to the -axis. These emissions are discussed in terms of the optical selection rule and exciton energies....
Localization of light is the photon analog of electron localization in disordered lattices, for whose discovery Anderson received the Nobel prize in 1977. The question about its existence in open three-dimensional materials has eluded an experimental and
We demonstrate that the 3.42 eV photoluminescence (PL) band in GaN is of the same intrinsic origin as the near-edge $\sim$3.47 eV band, but arises from regions of inversed polarity characterized by different strain and growth rate. Two absorption edges are thermally detected at 0.35 K in ...
We present a model calculation for the dependence of the near-band-edge photoluminescence (NBEPL) on the power of the exciting laser light. Our model explains all features of the NBEPL power dependence that were previously observed in experiment: (i) the variation of the excitonic photoluminescen...
