Abstract Sm3+ ions doped borosilicate glasses with variable concentration of Sm3+ ions (0.5 to 2.5 mol%) in steps of 0.5 mol% have been synthesized by using melt quench method. The X-ray diffraction (XRD), Fourier Transform Infrared (FT-IR) measurements were done for structure analysis. Broad hump in XRD determine the amorphous nature of the as prepared glass. The absorption spectra observed in UV-vis-NIR range and band gap has been determined to be in 3.011-3.020 eV range for all the prepared glasses. The photoluminescent (PL) excitation reveals 402 nm intense excitation peak and strong emission at around 600 nm as observed from PL spectral measurements. The colorimetric properties were studied to realize the utility of the glasses reported in this article for orange colour photonic device applications. The chromaticity diagram reveals orange emission with 0.594, 0.404 CIE coordinates. The PL decay spectral studies were utilised to acknowledge the type of energy transfer mechanism and illustrated dipole-dipole interaction between Sm3+ ions.
