On photoluminescence in HgGa2S4
Journal of Luminescence, 2005Abstract In this paper, we investigate the kinetics of photoluminescence in excited crystals of HgGa2S4 which have recently been proposed for implementing tunable luminescent devices. From photoluminescence experiments, performed at various temperatures and excitation powers, it appears that two kinds of radiative recombination processes take place ...

Il Nuovo Cimento B Series 11, 1974
The photoluminescence of a large number of pure and doped single crystals of GaSe has been investigated in the temperature range from 4.2 to 300 °K with excitation intensities varying between 4·10−5 and 3·102 kW cm−2. The excitation was produced by the green line of a frequency doubled Nd: YAG laser.

Achieving Near-Unity Photoluminescence Efficiency for Blue-Violet-Emitting Perovskite Nanocrystals
ACS Energy Letters, 2018While perovskite nanocrystals (NCs) have shown great promise as materials for efficient light-emitting diodes (LEDs), low photoluminescence quantum yield (PLQY) of the blue-emitting perovskites is an impediment to the development of white LEDs of which ...

Reciprocal-space analysis of photoluminescence and photoluminescence excitation spectra
Applied Physics Letters, 1996We show that energy positions of features in photoluminescence and photoluminescence excitation (PLE) spectra can be obtained more accurately by Fourier transforming segments of these spectra and analyzing the resulting coefficients in reciprocal space than by using conventional real-space analysis.

Photoluminescence of SrS:Cu phosphors
Solid State Communications, 1978Abstract Results of the investigation on the spectral characteristics of PL of SrS:Cu phosphors are presented. Probable emitters for the three observed bands, viz. 4710 A, 5200 A and 5480 A, have been suggested.

Photoluminescence and photoluminescence excitation spectra of GaAs grown directly on Si
Solid State Communications, 1986ABSTRACTThe photoluminescence of GaAs/Si grown by OMCVD has been analyzed as a function of temperature and the dominant high temperature line identified as a conduction-band-to-valence-band transition. Photoluminescence excitation spectra indicate that the transition is excitonic at 4.2 K.

Abstract The photoluminescence spectra of CuGaSe2 have been investigated at 76 K in the range 0.65 3 4 m grating monochromator. The luminescence observed consisted of a rather sharp structure near the energy gap, plus two broad peaks at considerably smaller energies.
