Article Preview

The aim of this study is to develop soda lime borate (SLB) doped with Dy3+ glass and investigate their optical and luminescence properties, for different applications in photonics and optoelectronics. The glass were melt by conventional melt quenching technique. Optical properties have been determined by measuring their absorption spectra and luminescence properties were studied by photo luminescence spectra. From optical absorption measurements, there are ten peaks with transition 6H15/2 to 6F11/2 + 6H9/2 at 1262 nm has higher spectral intensity and is a hypersensitive transition. As a result of 350 nm excitation the photoluminescence spectra have four peaks. Higher luminescence intensity peak was observed for 0.5 mol% Dy3+ doped SLB glass at 4F9/2 to 6H13/2 (575 nm). Hence it is suggest from the chromaticity results that SLB glasses with different Dy2O3 concentration may be a promising glass for white LED under 350 nm excitation wavelength. Further investigation is under way for the optimization of different dopend concentration in the SLB glass.
