Optical And Physical Analysis Of Borosilicate Glasses With Sm3+ Ions

Borosilicate glasses with composition 30B2O3 - 30 SiO2 – 10 Na2O – 20PbO – 10ZnO – 0.3Sm2O3 doped with Sm3+ ions were prepared by melt quenching technique. This works deals with structural, physical and fluorescence studies of borosilicate glasses. EDX has been used to establish the elemental composition of these materials. XRD confirms the amorphous nature of the glass materials and further confirmed by the SEM image. Structural information via vibrational modes was provided by FTIR spectra. TEM images give information about smooth surface of the glass material. Absorption and fluorescence spectra have been recorded. With their optical measurements various parameters have been computed. The value of spectroscopic quality factor is greater than one for present glass samples which shows the stability of the glass samples. CIE chromaticity diagram has been recorded for verifying the results of fluorescence and shows that the prepared glass samples give fluorescence in orange red region.
