While photoluminescent animals glow, they glow differently from bioluminescent animals, which generate light through chemical reactions. Instead, photoluminescence, which includes both biofluorescence ...

In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2021.210031 , Researchers led by Professor Andrei V. Lavrinenko and Dr Pavel N. Melentiev from the DTU Fotonik-Department of ...

Photoluminescence quantum yield (PLQY) is a fundamental parameter that quantifies the efficiency of the photoluminescence process in a material. It is defined as the ratio of the number of photons ...

Scientists are finding that photoluminescence is more common than previously suspected. Photograph by David Guttenfelder, Nat Geo Image Collection. By Jason Bittel. May 9, 2025.

No photoluminescence upon continuous wave excitations could be observed, unless the graphene is heavily doped to its one-photon Fermi edge resonance. In contrast to the continuous wave case, in the ...

Studying Alloyed Quantum Dots Using Absorption and Photoluminescence Spectroscopy. A range of alloyed QDs were examined via absorption and photoluminescence spectroscopy (see figure 2, below).

Photoluminescence is a spectroscopy process used to investigate electrical and optical qualities, such as emission wavelength, crystal structure, and defects in semiconductor materials. A ...

Confocal microscope image of waveguided photoluminescence in a hexagonal boron nitride waveguide. The lobe-pattern around the edges is reminiscent of koi circling a pond. Image taken by Samuel ...

A group of scientists from the University of New South Wales (UNSW), SMA Australia, and Gentari Solar Australia demonstrated a novel method for daylight photoluminescence (DPL) imaging using a ...

This video demonstrates the functioning of Imperia photoluminescence (PL) imaging system from Nanometrics. This PL system uses its unique optical design technology to detect and classify yield-killing ...
