Measurement and analysis of photoluminescence in GaN

, 2021
Photoluminescence (PL) spectroscopy is a powerful tool in studying semiconductor properties and identifying point defects. Gallium nitride (GaN) is a remarkable semiconductor material for its use in a new generation of bright white LEDs, blue lasers, and

In-situ investigations of the photoluminescence properties of SiO2/TiO2 binary and Boron-SiO2/TiO2 ternary oxides prepared by the sol-gel method and their photocatalytic reactivity for the oxidative decomposition of trichloroethylene

International Journal of Photoenergy, 2003
Photoluminescence behavior of TiO2, SiO2/TiO2 binary and Boron-SiO2/TiO2 ternary oxides prepared by the sol-gel method was investigated. The differences in their photocatalytic reactivities of TiO2-based photocatalysts were interpreted in terms of the ...

Photoluminescence of a Plasmonic Molecule [PDF]

ACS Nano, 2015
Photoluminescent Au nanoparticles are appealing for biosensing and bioimaging applications because of their non-photobleaching and non-photoblinking emission. The mechanism of one-photon photoluminescence from plasmonic nanostructures is still heavily debated though.

Photoluminescent Properties of CdTe Nanocrystals in Colloidal Solutions and Polymer Films

Фізика і хімія твердого тіла, 2017
Using stabilizers and promoters we have obtained colloidal CdTe nanocrystals (NCs) in aqueous solutions. Incorporation of the CdTe NCs into polymer films has been fulfilled subsequently. It is shown that the use of vinyl acetate-acrylate copolymer as the

Correlation between surface modification and photoluminescence properties of β-Ga2O3 nanostructures

AIP Advances, 2016
In this work three different growth methods have been used to grow β-Ga2O3 nanostructures. The nanostructures were characterized by Grazing Incident X-Ray Diffraction, Scanning Electron Microscopy, Transmission Electron Microscopy and Photoluminescence ...

Construction of online detection system for photoluminescence of perovskite thin films and research on the luminescence enhancement by light treatment

Gongneng cailiao yu qijian xuebao
Perovskite thin films fabricated through the solution process exhibit a significant number of internal defects. These defects serve as nonradiative recombination centers, markedly reducing photoluminescence intensity.

Electrochemically-stable ligands bridge the photoluminescence-electroluminescence gap of quantum dots [PDF]

Nature Communications, 2019
Colloidal quantum dots are promising emitters for quantum-dot-based light-emitting-diodes. Though quantum dots have been synthesized with efficient, stable, and high colour-purity photoluminescence, inheriting their superior luminescent properties in ...

Shallow defects and variable photoluminescence decay times up to 280 µs in triple-cation perovskites

Nature Materials
Quantifying recombination in halide perovskites is a crucial prerequisite to control and improve the performance of perovskite-based solar cells. While both steady-state and transient photoluminescence are frequently used to assess recombination in ...
