Ultrasound assisted rare earth doped Wollastonite nanopowders: labeling agent for imaging eccrine latent fingerprints and cheiloscopy applications

Abstract

Nano research offered new possibilities in surface-based science includes latent fingerprints and lips print detection on various surfaces. CdSiO3:Dy3+ nanopowders were fabricated via modified sonochemical method. Eccrine prints stained by optimized composition of prepared samples, exhibited high sensitivity, low background hindrance on various surfaces compared to traditional fluorescent powders. Surface morphologies were studied with different sonication influential parameters. Average crystallites size and band gap were 22 nm and 5.37 eV respectively. Photometric CIE and CCT values were close to near ultraviolet light with CP of 95% for the prepared compounds confirms their utility in the field of optoelectronics
