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
Red and green emitting CTAB assisted CdSiO3:Tb3+/Eu3+ nanopowders as fluorescent labeling agents used in forensic and display applications
R.B. Basavaraj,H. Nagabhushana,G.P. Darshan,B. Daruka Prasad,M. Rahul,S.C. Sharma,S.C. Sharma,R. Sudaramani,K.V. Archana +8 more
TL;DR: In this paper, rare earth (Tb or Eu) doped cadmium silicate nanopowders synthesized via eco-friendly ultrasound assisted sonochemical route as a substitute for the commercially available fluorescent powders were used for the visualization of latent fingerprints on various porous and non-porous surfaces.
Journal ArticleDOI
Novel and highly efficient red luminescent sensor based SiO 2 @Y 2 O 3 :Eu 3+ , M + (M + = Li, Na, K) composite core–shell fluorescent markers for latent fingerprint recognition, security ink and solid state lightning applications
K. N. Venkatachalaiah,K. N. Venkatachalaiah,H. Nagabhushana,G.P. Darshan,R.B. Basavaraj,B. Daruka Prasad +5 more
TL;DR: In this paper, powder dusting technique was used for the visualization of latent fingerprints (LFPs) on different porous and non-porous surfaces, the results display that the amorphous SiO2 microspheres were covered by crystalline Y2O3:Eu3+ Li+ NPs, resulting in spherical core-shell structure.
Journal ArticleDOI
Versatile core–shell SiO2@SrTiO3:Eu3+, Li+ nanopowders as fluorescent label for the visualization of latent fingerprints and anti-counterfeiting applications
A. Sandhyarani,M.K. Kokila,G.P. Darshan,R.B. Basavaraj,B. Daruka Prasad,S.C. Sharma,S.C. Sharma,T.K.S. Lakshmi,H. Nagabhushana +8 more
TL;DR: In this article, a core-shell NPs were used as fluorescent labeling agent for the visualization of latent finger prints and anti-counterfeiting applications, which revealed the detailed characteristic features such as lake, hook, island, bifurcation with high sensitivity, better selectivity and without background hindrance.
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.
