Significant spectral broadening of the photoluminescence in GaSe under the picosecond-laser-driven shock pressure has been observed for the first time. The broadening of the spontaneous emission was found to be proportional to the shock pressure and attributed to a shock-wave-induced exciton collision mechanism due to the directional motion of particles in the shocked region.

    Photoluminescence characterization of n-on-p Hg1-xCdxTe photodiodes formed by ion-milling technique shows that the luminescence peak of the n-type conversion region shifts remarkably toward higher energy with an amount of ∼40 meV more than that of the p region. The photovoltaic response of...

    We propose and experimentally demonstrate that a very simple, noninvasive, and common technique, i.e., standard nonresonant photoluminescence of large ensemble of quantum dots (QDs), can be used to determine the temperature dependence of homogeneous broadening. The method can be applied to a...

    In this paper we discuss a technique for broadening the emission and gain spectra of 1.3 μm quantum dot superluminescent light emitting diodes (SLEDs). By incorporating different amounts of indium in different wells of a multi-dot-in-well stack we are able to tailor the emission and gain...

    Through the photoluminescence (PL) measurements, we have studied the temperature dependence of the linewidth of PL spectra for type-II excitons in highly Si-doped GaAs/AlAs short-period-superlattices (SPS’s). In low temperature regions, we have observed the strong increase of the...

    The well-distinguished lower polariton branches (LPBs) and upper polariton branches (UPBs) are characteristics of strong coupling in semiconductor microcavities (MCs). In practice, however, the UPBs are often broadening especially in wide-bandgap material MCs. We present in detail the possible...
