Optical Characterization of Eu3+ Ions in CdSe Nanocrystal Containing Silica Glass
TL;DR: The phonon sideband spectrum associated with the excitation transition 7F0−5D2 is used to analyze the electron–phonon coupling and nonradiative deexcitiation of the rare earth ions in the glass host.

TL;DR: The structural and optical properties of Eu3+/CdSe nanocrystals in silica galss are presented in this paper, where the phonon sideband spectrum (PSB) associated with the excitation transition 7F0-5D2 is used to determine the electron-phonon coupling constant and non-radiative de-excitation rate of the rare earth ions.
Journal ArticleDOI
Fluorescence enhancement from Eu3+ ions in CdSe nanocrystal containing silica matrix hosts
TL;DR: In this paper, the effect of nanocrystals on the absorption and fluorescence features of europium ions is discussed, and the fluorescence spectra reveal that the intensity of characteristic emission of Europium increases considerably in the presence of CdSe particles.
Journal ArticleDOI
Studies on the growth and optical characterization of dysprosium gadolinium oxalate single crystals
TL;DR: In this article, the authors describe the preparation and optical characterization of dysprosium praseodymium oxalate (DPO) single crystals using a silica gel technique.
Journal ArticleDOI
Structural and optical characterization of CdSe nanocrystallites/rare earth ions in sol–gel glasses
TL;DR: In this article, electron diffraction pattern in the transmission electron micrograph (TEM) was estimated to be 1.072 A, 1.233 A and 2.149 A, which match the (2 −1 4), (3 −0 −0) and (1 −1 0) planes of bulk CdSe.
