Luminescence Properties of Dy3+-doped Lutetium-Calcium-Silico-Borate Glasses for White Light Emitting Applications

Lutetium-calcium-silico-borate glasses doped with various concentrations of dysprosium ions (Dy 3+ ) have been fabricated. The amorphous nature of glasses has been confirmed by XRD technique. The luminescence properties have been studied throughout the emission spectra, the combination of blue and yellow emissions was shown for all the glasses and white light emission could be observed. The x, y coordinates of the prepared glasses pass through the white light region in the CIE 1931 diagram and are suitable for white light emitting devices.
