Red luminescent Eu3+ activated CaSiO3 phosphor has been prepared by facile green synthesis hydrothermal route using biomass. Future technologies will be required to synthesize on a massive scale using quick, easy, and affordable ways. The current study deals with the preparation of CaSiO3:Eu3+ using egg shell and rice husk ash. The synthesized powders had a single phased monoclinic structure with space group P1 21/C1. It has been found that addition of Eu3+ ion dopant causes decrease in the optical energy band gap. The phosphor exhibits the intense peak at 612 nm corresponds to 5D0 → 7F2 of the Eu3+ anions upon excitation at 392 nm. The lifetimes ranged from 1.90 to 3.53 ms. With an increase in Eu3+ concentration, emission was tuned towards the red area of the CIE diagram. In order to detect hidden fingerprints on flat surfaces using the powder dusting approach, the CaSiO3:Eu3+ effectiveness was also evaluated. The nontoxicity of CaSiO3:Eu3+ was validated by carrying out a cell viability test on MG 63 cell lines. These outcomes demonstrated that the luminescent CaSiO3:Eu3+ can be used as potential material for display, security encoding, and latent fingerprint applications. |
