“…The trivalent samarium ion (Sm 3+ ) is one of the most important active ions in the RE family due to its closely lying energy level structure [17]. The 4 G5/2 level of Sm 3+ has a relatively high quantum efficiency which shows luminescence in the orange and red regions of the visible spectrum via transitions to the ground state 6 H5/2 or to the higher energy states 6 Hj [(j = 7/2, 9/2, and 11/2) [17]. Although there have been a large number reports on various rare earth doped glassy systems, the synthesis and optical analysis of samarium doped bismuth silicate glasses have seldom been studied.…”

Detailed optical spectroscopic studies of the glassy material were carried out in the UVVis-NIR spectral range. Our analysis revealed that the novel glassy system has the optimum values for the key parameters viz. spectroscopic quality factor, optical gain, stimulated emission cross section and quantum efficiency, which are required for a high performance optical amplifier. Calculated chromaticity co-ordinates (0.61, 0.38) also confirm its application potential in display devices.

“…The addition of heavy metal oxide causes deformation of borate building groups of glass matrix. The observed absorption band at about 674 cm À1 is assigned to bending vibrations of BO 3 triangles and stretching vibrations of BO 3 units with non bridging oxygens [13,41] band at 2925-3455 cm À1 is due to the O-H stretching vibrations and confirms the presence of OH groups in the glass composition [13,41].…”

“…However, beyond 1 mol% Sm2O3, the intensity is quenched by a factor of 1.83:1.53:1.61:1.76 times for all the transition bands. This quenching is due to the decrease in distance between Sm 3+ ions which would implies the energy transfer ng Sm 3+ ions due to the existence of inter-atomic interaction [16]. A similar approach has also previously been done in the Sm 3+ doped magnesium tellurite glasses [10].…”

Estimation of mean glandular dose for patients who undergo mammography and studying the factors affecting it AIP Conference Proceedings 1888, 020020 (2017) Abstract. Series of glasses based on (70-x) TeO2 -20Na2O -xSm2O3 (x=0, 0.3, 0.6, 1, 1.2, 1.5 mol%) have been prepared using melt-quenching technique. The nature of the glass has been confirmed using X-ray diffraction; it is found that the glass samples are amorphous in nature. The thermal stability of the glass has been determined by means of Differential Thermal Analysis (DTA). From the DTA curve, the glass transition temperature (Tg), crystallization temperature (Tc) and melting temperature (Tm) have been identified and thermal stability is also calculated. The absorption properties of these samples are obtained by using UV-Visible-NIR spectrometer, the recorded absorption spectra exhibit nine absorption transition bands peaks corresponding to the transitions from ground level 6 H5/2→ 6 P3/2, 4 I11/2, 6 F11/2, 6 F9/2, 6 F7/2, 6 F5/2, 6 F3/2, 6 H15/2 and 6 F1/2. The emission characteristic of this glass is characterized using Photoluminescence (PL) spectroscopy at excited wavelength 404 nm, the emission spectra consisted of four emission bands at 561.95 nm, 598.69 nm, 643.77 nm and 704.56 nm which were assigned as a transition 4 G5/2→ 6 H5/2, 6 H7/2, 6 H9/2 and 6 H11/2 respectively. From f-f intensity model the experimental oscillator strengths, fexp and theoretical oscillator strength fcal were calculated. Using Judd-Ofelt theory and fit process of least square, the phenomenological intensity parameters Ωλ (λ=2,4,6) were obtained, In order to evaluate potential applications of Sm 3+ ions in telluride glasses, the spectroscopic parameters: transition probability AR, branching ratio Br, radiative life time τr, emission pick cross section σλ for each band were calculated. The comparative studies with other Sm 3+ doped different glasses showed that present glasses could be a potential candidate for lasers.
