Physical, Optical and Luminescence Properties of Er3+-Doped Bismuth Borosilicate Glasses

Er3+-doped bismuth borosilicate glasses (Bi2O3+B2O3+SiO2+Er2O3) glasses doped with different Er2O3 concentrations (0, 0.50, 1.00, 1.50, 2.00, 2.50 mol%) have been prepared by melt quenching technique and their physical, optical and luminescence properties have been studied. The density of glasses showed the highest value at 4.7358 g/cm3 with 1.00 mol% of Er2O3. The optical absorption spectra of glasses were observed seven bands at 488, 523, 543, 654, 801, 975 and 1529 nm which assigned to the transitions 4I15/2→4F7/2, 2H11/2, 4S3/2, 4F9/2, 4I9/2, 4I11/2 and 4I13/2, respectively. The emission spectra of glasses were also investigated and discussed in term of energy level of Er3+ ion in glass matrices.

Glass Properties

This paper reports neodymium doped bismuth borosilicate glasses in composition (40-x)B2O3-40Bi2O3-20SiO2-xNd2O3 where x = 0, 0.5, 1.0, 1.5, 2.0 and 2.5 mol%, have been prepared by melt quenching technique and are characterized through physical properties structural properties, optical absorption spectra and emission spectra measurements. The density is found to increase with the increase in concentration of Nd2O3. The molar volumes of glass decrease where concentration of Nd2O3 where concentration of Nd2O3 is 0-0.5 mol% and beyond 0.5 mol% that molar volumes were increased. The absorption spectra of Nd3+-doped glass centered at 512 nm (4I9/2→2K13/2+4G9/2), 526 nm (4I9/2→4G7/2), 584 nm (4I9/2→4G5/2+2G7/2), 625 nm (4I9/2→2H11/2), 681 nm (4I9/2→4F9/2), 747 nm (4I9/2→4F7/2+4S3/2), 804 nm (4I9/2→4F5/2+2H9/2) and 877 nm (4I9/2→4F3/2) have been observed. The emission spectra of glass were also investigated.

In this work, properties of Nd3+ in Gd2O3-CaO-SiO2-B2O3 glass systems with composition 25Gd2O3-10CaO-10SiO2-(55-x)B2O3-xNd2O3 where x = 0.0, 0.5, 1.0, 1.5, 2.0 and 2.5 mol% were investigated. The optical absorption spectra show peaks at 4F3/2 (877 nm) , 4F5/2+2H9/2 (802 nm), 4F7/2+4S3/2 (743 nm), 4F9/2 (682 nm), 2H11/2 (627 nm), 2G7/2 +4G5/2 (582 nm), 4G7/2 +2K13/2 (527 nm), 4G11/2 (481 nm), 2P1/2 (427 nm) and 2L15/2 + 4D1/2 + 1I11/2+ 4D5/2+ 4D3/2 (355 nm) reflecting the Nd3+ ions in glass matrices. The densities were increased with increasing of Nd2O3 concentration. This indicates the increase of the molecular weight by the replacement of B2O3 with a heavier Nd2O3 oxide in the glass. The upconversion luminescence spectra show bands at 393 nm for all Nd2O3 concentration and the strongest intensity from 2.5 % mol of Nd2O3 was obtained. For NIR luminescence, the intensity of Nd3+ emission spectra increases with increasing concentrations of Nd3+ up to 1.5 mol% and beyond 1.5 mol% the concentration quenching is observed.

Work Effect

In this work, effect of Li2O and Na2O on bismuth borate glasses have been investigated. The glass samples were prepared in composition 44B2O3 : 50Bi2O3 : 5Li2O : 1A2O3 and 44B2O3 : 50Bi2O3 : 5Na2O3 : 1A2O3 (where A2O3= Sm2O3 and Dy2O3).Glasses were prepared using the melt-quenching technique at 1,100 oc under normal atmosphere. The result found that, the density and molar volume of lithium bismuth borate glasses are less than sodium bismuth borate glasses both in Sm2O3 and Dy2O3. In addition, the optical absorption spectra and luminescence of lithium bismuth borate glasses are higher than sodium bismuth borate glasses both in Sm2O3 and Dy2O3.

Mobility Gap

Glasses with composition xCdO-(40-x) Na2CO3-60H3BO3; x = 10, 20, 30 and 40 mol% were prepared by conventional melt-quenching technique and checked by XRD technique for their amorphous nature. An increase in density and refractive index of the samples with an increase in content of CdO has been observed and discussed. The optical absorption spectra of the glasses were recorded in the range 200–1100 nm and was used to find optical mobility gap, Urbach energy, and cut-off wavelength for each sample. The decrease in optical mobility gap with increase in CdO points towards the compactness of the structure with the addition of CdO. FTIR spectroscopy reveals the presence of trigonal and tetrahedral borate units, and the results indicate the conversion of BO3 to BO4 units with the increase in CdO content.
