Journal ArticleDOI
Effective fingerprint recognition technique using doped yttrium aluminate nano phosphor material
TL;DR: A simple, fast, highly sensitive and low-cost method for the detection and enhancement of fingermarks in a broad range of surfaces is developed and constitutes an alternative to traditional luminescent powders.
Journal ArticleDOI
Superstructures of doped yttrium aluminates for luminescent and advanced forensic investigations
G.P. Darshan,H.B. Premkumar,H. Nagabhushana,S.C. Sharma,B. Daruka Prasad,S.C. Prashantha,R.B. Basavaraj +6 more
TL;DR: In this paper, a simple, fast, highly sensitive and ecofriendly method for the detection and enhancement of fingermarks in various forensic relevant materials was presented, which is very close to NTSC standard value for green emission.
Journal ArticleDOI
Blue light emitting ceramic nano-pigments of Tm3+ doped YAlO3: Applications in latent finger print, anti-counterfeiting and porcelain stoneware
G.P. Darshan,H.B. Premkumar,H. Nagabhushana,S.C. Sharma,S.C. Prashantha,H.P. Nagaswarup,B. Daruka Prasad +6 more
TL;DR: In this article, a new class of ceramic pigments based on orthorhombic Thulium (Tm 3+ ) doped YAlO 3 nanophors are synthesized by a simple and efficient low temperature solution combustion method using oxalyl dihydrazide (ODH) as fuel.
Journal ArticleDOI
A benign approach for tailoring the photometric properties and Judd-Ofelt analysis of LaAlO3:Sm3+ nanophosphors for thermal sensor and WLED applications
T. Manohar,S.C. Prashantha,Ramachandra Naik,H. Nagabhushana,H.P. Nagaswarupa,K.S. Anantharaju,K.M. Girish,H.B. Premkumar +7 more
TL;DR: In this paper, the luminescence properties of Lanthanum aluminate (LaAlO 3 ) nanophosphor have been investigated and the estimated branching ratio (∼56%) was greater than 50%.
Journal ArticleDOI
Facile EGCG assisted green synthesis of raspberry shaped CdO nanoparticles
H. Nagabhushana,R.B. Basavaraj,B. Daruka Prasad,S.C. Sharma,H.B. Premkumar,Udayabhanu,G.R. Vijayakumar +6 more
TL;DR: In this article, a green synthesis method was adopted for the preparation of raspberry shaped CdO nanoparticles (NPs) using extract of green tea leaves as a non-toxic and eco-friendly fuel.
