Efficient reddish-orange emitting zinc telluro-phospho-borate: Sm3+ glasses for photonic devices

Abstract

Samarium (Sm3+)-doped glass materials have attracted the interest of many researchers owning to its noticeable emission from 400 to 700 nm spectral zone. Thus, the present study reports the optical qualities of Sm3+ doped telluro-phospho-borate (BTPZSm) glass matrix. The glasses were made via melt quenching approached and examined by absorption, luminescence, and fluorescence decay time, respectively. The absence of sharp peaks from the XRD contour certified the non-crystalline nature of the as-produced glasses. From the emission spectra, reddish-orange (coral) luminescence at 4G5/2→6H7/2, 600 nm was attained with emission quenching observed beyond 1 mol% content of Sm3+. Further, various radiative entities were computed by utilizing Judd-Ofelt parameters whereas decay profiles exhibit single-exponential shape. Instantaneously, the deduced CIE chromaticity coordinates for BTPZSm1.0 sighted around reddish-orange region with an inspiring color purity (84.2 %) alongside the accomplished fashionable radiative qualities justify the readiness of our current glasses for developing new visible photonic devices.
