Journal ArticleDOI
Sunlight-activated Eu2+/Dy3+ doped SrAl2O4 water resistant phosphorescent layer for optical displays and defence applications
TL;DR: In this article, the authors introduced a strategy for the fabrication of a sunlight-activated green luminescent Eu2+/Dy3+ doped strontium aluminate (Sr1−x−yAl2O4:Eux2+ /Dyy3+) assisted long persistent, transparent, flexible and water resistant phosphorescent layer via a customized solid state reaction-solution casting method.
Journal ArticleDOI
A commercial approach for the fabrication of bulk and nano phosphors converted into highly efficient white LEDs
Jaya Dwivedi,Pawan Kumar,Arun Kumar,Sudama Sudama,V.N. Singh,Bhanu Pratap Singh,Sundeep Kumar Dhawan,Virendra Shanker,Bipin Kumar Gupta +8 more
TL;DR: In this article, a strategy to synthesize a highly efficient yellow light emitting Y3−xAl5O12:Cex (x = 0.03 to 0.3) based bulk as well as nano (rod-shaped) phosphors, which are the main component of solid state white light-emitting diodes (WLEDs), was reported.
Journal ArticleDOI
SnS Thin Film Solar Cells: Perspectives and Limitations
Simone Di Mare,Daniele Menossi,Andrei Salavei,Elisa Artegiani,Fabio Piccinelli,Arun Kumar,Gino Mariotto,Alessandro Romeo +7 more
TL;DR: In this article, the limitations of SnS deposition in terms of reproducibility and reliability were analyzed by X-ray diffraction, Raman spectroscopy, scanning electron microscopy, and atomic force microscopy.
Journal ArticleDOI
Influence of deposition time on the properties of ZnS/p-Si heterostructures
TL;DR: In this article, the structural, morphological and optical properties of ZnS/p-Si heterostructures have been thoroughly investigated using X-ray diffraction, x-ray photoelectron spectroscopy, scanning electron microscopy, UV-visible and photoluminescence spectrography.
Journal ArticleDOI
Highly responsive and low-cost ultraviolet sensor based on ZnS/p-Si heterojunction grown by chemical bath deposition
Arun Kumar,Manjeet Kumar,Vishwa Bhatt,Samrat Mukherjee,Sunil Kumar,Himanshu Sharma,Monu Yadav,S.K. Tomar,S.K. Tomar,Ju-Hyung Yun,Ravi Kant Choubey +10 more
TL;DR: In this paper, nanocrystalline ZnS thin films were deposited on p-Si substrates, and the crystalline quality of the as-deposited thin films was studied using X-ray diffraction and scanning transmission electron microscopy (STEM).
