Journal ArticleDOI
Emerging cool white light emission from Dy3+ doped single phase alkaline earth niobate phosphors for indoor lighting applications
Amit K. Vishwakarma,Kaushal Jha,M. Jayasimhadri,B. Sivaiah,B. Sivaiah,Bhasker Gahtori,Bhasker Gahtori,D. Haranath +7 more
TL;DR: The study reveals that BaNb2O6:Dy(3+) phosphor could be a potential candidate for near ultra-violet (NUV) excited white-LED applications and chromaticity coordinates and correlated color temperature (CCT) endorse cool white-light emission from the phosphor.
Journal ArticleDOI
Spectroscopic investigation on thermally stable Dy3+ doped zinc phosphate glasses for white light emitting diodes
Kaushal Jha,M. Jayasimhadri +1 more
TL;DR: In this article, the luminescent properties and their applications for white light emitting diodes (w-LEDs) were investigated using X-ray diffraction (XRD) pattern confirmed the amorphous nature of the as-prepared glass.
Journal ArticleDOI

Lokesh Mishra,Anchal Sharma,Amit K. Vishwakarma,Kaushal Jha,M. Jayasimhadri,B.V. Ratnam,Kiwan Jang,A.S. Rao,Ravindra Kumar Sinha +8 more
TL;DR: In this paper, the synthesis of Dy3+ doped barium silicate glasses, along with subsequent studies performed to evaluate its viability in solid state lighting applications, were elucidated via X-Ray Diffraction, Scanning Electron Microscopy and Fourier Transform Infrared Spectroscopy.
Journal ArticleDOI
Structural and emission properties of Eu3+-doped alkaline earth zinc-phosphate glasses for white LED applications
Kaushal Jha,M. Jayasimhadri +1 more
TL;DR: In this paper, a set of quaternary alkaline earth zinc-phosphate glasses in molar composition (40 − x) ZnO-35P2O5-20BaO-5TiO2- xEu2O3 (x=1 and R=Mg, Ca, Sr, and Ba) were prepared by melt quenching technique.
Journal ArticleDOI
