“…According to the X-ray diffraction (XRD) analysis, it has been determined that the glass samples exhibit a lack of regular, uniform atomic arrangement typically observed in crystalline materials. This finding provides evidence that the glass samples are entirely amorphous in nature [20]. The prominent hump observed within the angular span of 20 o to 40 o is indicative of the broad peak exhibited by glasses, which can be attributed to the variation of inter-atomic spacing.…”

Er+ 3doped lead-bismuth tellurite glasses with the composition (75-x) TeO2 − 15 PbO – 10 Bi2O3 - xEr2O3 where (x = 0, 0.5, 1, 1.5, 2 and 2.5 mole%) were synthesized by using melt quenching technique. The influence of Er3+ doping was evaluated through physical and optical properties. The non-crystalline nature of the samples was analyzed by XRD. The density of the samples was increased from 6.387 to 6.528 g.cm− 3. The absorption spectra show eight transition bands corresponding to the transitions from 4I15/2 to 4I13/2, 4I11/2, 4I9/2, 4F9/2, 4S3/2, 4H11/2, 4F7/2 and 4F5/2, respectively. The experimental and calculated oscillator strengths were calculated based on the Judd-Ofelt theory. The intensity parameters follow the trend Ω2 > Ω6 > Ω4. Three emission bands were observed from the fluorescence spectra. The green transition 4S3/2 →4I15/2 is the strongest among other transitions. The color coordinates were determined by using CIE 1931 chromaticity diagram. The highest quantum efficiency was 95.11% for the transition 4S3/2 →4I15/2. The results suggest that the TPBE2 glass is a great promising candidate for photonic applications and fabrication of laser optical devices.

“…A 10 g batch was homogenized by subjecting the batch to a ball milling machine for 20 min. The mixtures were melted in an alumina crucible in an electrical furnace at 1000 °C for 25 min by melt-quench technique [ 25 ]. Melt quenching is a common technique used in glassmaking to create glass from a mixture of raw materials.…”

“…However, B 2 O 3 reduces the quantity of bridging oxygens (BOs) in PO 4 units with negative charge. [14,16,17] The addition of the modifier (Al 2 O 3 ) to the network also improves the physical and optical characteristics of the glasses and enhances their strength. [18,19] In addition, by adding alkali oxide, it is possible to change the host structure and increase the physical properties, glass-forming capacity, luminescence intensity, and moisture resistance by produced NBOs, beneficial for the stability of the glass system.…”

The optical, photo, and X-ray luminescence properties of Sm 3þ ion-doped Li 2 O-Al 2 O 3 -Gd 2 O 3 -B 2 O 3 -P 2 O 5 glasses are evaluated. The glasses are fabricated by the melt quenching technique. The absorption spectra exhibit the hypersensitive transitions 6 H 5/2 ! 6 P 3/2 and 6 H 5/2 ! 6 F 7/2 at the visible and near-infrared range respectively. The glasses display four major transitions characteristic of Sm 3þ ion for photoluminescence and X-ray luminescence, with the most intense one corresponding to the 4 G 5/2 ! 6 H 7/2 transition. The best emitting samarium concentration obtained by X-ray excitation is compared to BGO crystals. The integral scintillation efficiency of glass is determined by total area under all of peak spectrum. The results indicate the promising application of these glasses in scintillators and for X-ray sensing devices.
