Near-ultraviolet excited down-conversion Sm3+-doped Ba5Zn4Gd8O21 reddish-orange emitting nano-diametric rods for white LEDs
Sushma Devi,Mandeep Dalal,Jyoti Dalal,Anju Hooda,Avni Khatkar,V.B. Taxak,Satyender P. Khatkar +6 more
TL;DR: In this article, the structural and morphological characterizations were systematically done via X-ray diffractometry (XRD) and transmission electron microscopy (TEM). Refined atomic positions as well as unit cell parameters for optimum composition were calculated using refinement technique.

Optical properties of trivalent samarium-doped Ba5Zn4Y8O21 nanodiametric rods excitable by NUV light
Sushma Devi,Avni Khatkar,V.B. Taxak,Mandeep Dalal,Sangeeta Chahar,Jyoti Dalal,Satyender P. Khatkar +6 more
TL;DR: A series of nanophosphors were synthesized via urea-assisted solution combustion method and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), diffuse reflectance (DR), and photoluminescence (PL) spectroscopy as mentioned in this paper.

Structural analysis and Judd-Ofelt parameterization of Ca9Gd(PO4)7:Eu3+ nanophosphor for solid-state illumination
Jyoti Dalal,Mandeep Dalal,Sushma Devi,Rekha Devi,Anju Hooda,Avni Khatkar,V.B. Taxak,Satyender P. Khatkar +7 more
TL;DR: In this article, a trigonal crystal system with R3c(161) space-group symmetry and high brightness, red-emitting Ca9Gd1−x(PO4)7:xEu3+ phosphors were developed via the facile route of solution-combustion.
