Spatially Resolved Optical Efficiency Measurements of Luminescent Solar Concentrators.

open access: yes, 2023
Luminescent solar concentrators (LSCs) are able to concentrate both direct and diffuse solar radiation, and this ability has led to great interest in using them to improve solar energy capture when coupled to traditional photovoltaics (PV). In principle,

Preliminary Investigation on the Physiology and Ecology of Luminescence in the Copepod, Metridia lucens [PDF]

open access: yes, 1961
1. Skin glands believed to be the source of luminescence were found on the anterior portion of the head, on the last thoracic segment, and on the posterior margins of each segment of the abdomen. 2. The maximum intensity of the luminescent flash was 1.2

Spatially-resolved measurement of optically stimulated luminescence and time-resolved luminescence [PDF]

open access: yesRadiation Measurements, 2003
Spatially-resolved measurements of optically stimulated luminescence (OSL) were performed using a two-dimensional scanning system designed for use with planar samples. The scanning system employs a focused laser beam to stimulate a selected area of the sample, which is moved under the beam by a motorised stage.

Image-Processing Software for High-Throughput Quantification of Colony Luminescence

open access: yesmSphere, 2019
Many microbiological assays include colonies that produce a luminescent or fluorescent (here generalized as “luminescent”) signal, often in the form of luminescent halos around the colonies.

N,N-Dimethyl-4-amino-2,1,3-benzothiadiazole: Synthesis and Luminescent Solvatochromism

open access: yesChemistry Proceedings, 2021
N,N-Dimethyl-4-amino-2,1,3-benzothiadiazole (BTDNMe2) was synthesized from the commercially available 2,1,3-benzothiadiazole (BTD) by nitration in a sulfonitric mixture, followed by a reduction of the nitro group and subsequent methylation with ...

Luminescence measurement of band gap [PDF]

open access: yesActa Physica Sinica, 2022
Optical band gap or band gap is an important characteristic parameter of semiconductor materials. In this study, several representative InGaN/GaN multiple quantum well structures are taken as the research objects, and the test conditions that need to be met for the luminescence measurement of the optical band gap of the InGaN well layer at a certain ...
