| Summary: | Borate materials are very beneficial for optical materials due to its wide transparency range, huge electronic band gap, thermal and chemical durability, low preparative temperature, and high optical damage threshold. Na3SrB5O10 glasses were synthesized through a melt quenching technique followed by a sintering process, incorporating various concentrations of Eu3+ ions. The XRD pattern of the prepared glass sample indicates an amorphous pattern, vibrational feature of the prepared glass sample has been investigated using FT-IR analysis. Photoluminescence study of Eu3+ activated Na3SrB5O10 glass sample shows multiple emission peaks under NUV excitations in the red region. The prepared glass samples show orange-red emission bands at 595 nm and 615 nm, respectively, under the excitation of 395 nm and 465 nm. The red emission band is stronger than the orange emission band. The intense emission band was detected for doping of 2.5 mol% concentration of Eu3+ ions. In addition, CIE color coordinate, color purity and color correlated temperature (CCT) were determined using color calculator. The above results suggested that the Eu3+-activated Na3SrB5O10 glass samples have huge potential for lighting and display applications. |
