Photoluminescence and photoluminescence excitation spectroscopy in ordered and disordered Ga0.52In0.48P

AIP Conference Proceedings, 1992
The band gap of Ga0.52In0.48P varies considerably, depending on conditions of growth. This is a result of ordering in the CuPt structure. Details of the ordering also lead to more subtle optical effects. We report here on photoluminescence (PL) and photoluminescence excitation (PLE) measurements on ordered and disordered Ga0.52In0.48P.

Reciprocal-space analysis of photoluminescence and photoluminescence excitation spectra

Applied Physics Letters, 1996
We 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, 1978
Abstract 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.

Achieving Near-Unity Photoluminescence Efficiency for Blue-Violet-Emitting Perovskite Nanocrystals

ACS Energy Letters, 2018
While 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 ...

The Photoluminescence of Flames

Physical Review, 1923
Effect of light on the intensity of the flame spectra of Li, Na, Ca, and Sr.---The salted flame of an air-hydrogen blast lamp was illuminated with the full light from a tungsten lamp, a carbon arc, a mercury arc and an iron spark, and the intensity of the bands or lines emitted, as determined by a photometric balance method in connection with a ...
