Structural and luminescence properties of Sm³⁺‐doped bismuth phosphate glass for orange‐red photonic applications

Abstract

In the present study, the effect of bismuth oxide (Bi O ) content on the structural and optical properties of 0.5Sm -doped phosphate glass and the effect of concentration on structural and optical properties of Sm -doped bismuth phosphate (BiP) glass were studied. Structural characterization was accomplished using X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), Fourier transform infrared (FTIR) spectroscopy and P nuclear magnetic resonance (NMR) spectroscopy. Optical properties were studied using absorption, photoluminescence and decay measurements. Using optical absorption spectra, Judd-Ofelt parameters were derived to determine the local structure and bonding in the vicinity of Sm ions. The emission spectra of Sm -doped BiP glass showed two intense emission bands, G → H (orange) and G → H (red) for which the stimulated emission cross-sections (σ ) and branching ratios (β) were found to be higher. The quantum efficiencies were also calculated from decay measurements recorded for the G level of Sm ions. The suitable combination of Bi O (10 mol%) and Sm (0.5 mol%) ions in these glasses acted as an efficient lasing material and might be suitable for the development of visible orange-red photonic materials.

Spectroscopic and Radiative Properties of Sm3+ Doped Sodium-Lead-Zinc-Lithium-Borate Glasses

“…The decay times obtained were 3.42, 3.99, 3.98, 2.96, 1.67, 1.48 ms for 0.05, 0.1, 0.5, 1.00, 2.00 and 4.00 mol% of Sm2O3 doped in borate glass, respectively. The lifetime decreases when the Sm2O3 concentration increases due to an increase in the energy transfer process of the Sm 3+ ion [11,40]. From these coordinates it shows that all Sm2O3 glass samples emit the same emission coordinates of the light emission, so that all coordinates can be approximated to (0.59, 0.40).…”

“…Damodaraiah et al prepared Sm 3+ doped Bismuth phosphate glass by traditional melt quenching method. The results show that the combination of 10mol% Bi 2 O 3 and 0.5mol% Sm 3+ ions in Bismuth phosphate glass is an effective orange-red photonic material [7].

Influence of Oxide Glass Modifiers on the Structural and Spectroscopic Properties of Phosphate Glasses for Visible and Near-Infrared Photonic Applications

“…Among the different inorganic glass systems, phosphate glasses have been studied for numerous industrial applications [ 24 , 25 ] and for broad optical applications in the range of visible luminescence [ 26 , 27 , 28 , 29 , 30 ] and infrared luminescence [ 31 , 32 , 33 , 34 , 35 ]. These glass materials containing rare earth ions such as Nd 3+ , Yb 3+ , Er 3+ can be successfully used for high-power laser systems, optical amplifiers and optical sensors due to their excellent luminescent properties [ 36 , 37 , 38 , 39 , 40 , 41 , 42 ].…”
