Photoluminescent Properties of CdTe Nanocrystals in Colloidal Solutions and Polymer Films

open access: yesФізика 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

open access: yesAIP 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

open access: yesGongneng 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.

Nonoxide Sol-Gel Synthesis of Terbium-Doped Silicon Nitride Phosphors

open access: yes, 2009
Exposure of solutions of Tb(N(SiMe3)2)3 with SiCl(NEt2)3 in tetrahydrofuran to dry ammonia results in polymeric xerogels. Heating these gels in ammonia leads to amorphous Tb:SiNx phosphors that exhibit bright green luminescence under UV irradiation.

Photoluminescence-Driven Broadband Transmitting Directional Optical Nanoantennas

open access: yes, 2018
Optical nanoantennas mediate near and far optical fields. Operating a directional nanoantenna in transmitting mode is challenging because the antenna needs to be driven by a nanosized optical frequency generator, which must work at the antenna’s ...
