Journal ArticleDOI
Influence of doping and annealing temperature on the structural and optical properties of Mg2SiO4:Eu3+ synthesized by combustion method
TL;DR: In this article, the structural and optical properties of europium doped magnesium orthosilicate nanophosphor were investigated by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Field emission scanning electron microscope (FESEM), High resolution Transmission electron microscopy (HRTEM), Diffuse Reflectance Spectra (DRS), and Photoluminescence spectra (PL) together with decay time.
Journal ArticleDOI
Enhanced red emission on co-doping of divalent ions (M2+ = Ca2+, Sr2+, Ba2+) in YVO4:Eu3+ phosphor and spectroscopic analysis for its application in display devices
Puja Kumari,J. Manam +1 more
TL;DR: The photometric characterizations and corresponding calculations indicated the suitability of the phosphor for display devices, and divalent ions introduced radiative defect centers, which enhances the PL intensity significantly.
Journal ArticleDOI
Structural, optical and special spectral changes of Dy3+ emissions in orthovanadates
Puja Kumari,J. Manam +1 more
TL;DR: In this article, the structural, optical and photometric characterization of yttrium gadolinium orthovanadates (Y1−xGdxVO4) doped with Dy3+ for white emission in solid state lighting was reported.
Journal ArticleDOI
Effects of morphology on the structural and photoluminescence properties of co-precipitation derived GdVO 4 :Dy 3+
Puja Kumari,J. Manam +1 more
TL;DR: In this paper, Dy 3+ doped GdVO 4 samples with various morphologies were prepared by the co-precipitation method at low temperature, and the effects of different morphologies on the structural and optical behaviors have been reported.
Journal ArticleDOI
Influence of Dy 3+ ions doping on structural and luminescent properties of GdVO 4
Puja Kumari,J. Manam +1 more
TL;DR: In this article, the effects of Dy3+ doping concentration on the structural and photoluminescence properties of dy3+ activated tetragonal GdVO4 matrix, synthesized via the co-precipitation method, have been presented in detail.
