What is A highly intense double perovskite BaSrYZrO5.5: Eu3+ phosphor for latent fingerprint and security ink applications about?

A novel double perovskite BaSrYZrO 5.5 :Eu 3+ red-emitting phosphor was synthesized and characterized by XRD, SEM and PL analyses. The structure of the prepared phosphor was confirmed through JCPDS as well as Rietveld refinement analysis. The present phosphor shows an intense red emission at 613 nm when excited by 394 nm. The CIE colour coordinates value of BaSrYZrO 5.5 :Eu 3+ (9 mol%) phosphor is found to be (0.6181, 0.3783) and it has high colour purity of 99.1%. The 613 nm transition integrated intensity of the present phosphor is 4.44 times higher compared to the commercial red phosphor. The thermal stability and Quantum yield of optimized BSYZ: Eu 3+ (9 mol%) phosphor were also calculated. The BSYZ:Eu 3+ phosphor results can be employed as an efficient red component in latent fingerprint detection and anti-counterfeiting applications.
