| description | A series of zinc borosilicate glass doped with dysprosium oxide (Dy-ZBS) has been successfully
fabricated through the conventional melt-quench technique with the incorporation of bio-silica
source from rice husk ash. The physical, structural, luminescence, and optical properties of the
fabricated glass have been studied utilizing the bulk density, x-ray diffraction pattern, photoluminescence emission spectra, chromaticity coordinates, absorption spectra, and optical band
gap. The bulk density improved from 3.468 gcm− 3 to 3.635 gcm− 3 as the dopant concentration
increased due to the compactness of the network structure. The amorphous nature of the glass has
been justified by using an X-ray diffraction pattern. Whereas the photoluminescence emission
spectra have been confirmed the presence of blue and yellow colors and were intensified as the
Dy3+ increases. The CCT values from chromaticity diagram of the best white light-reaching coordinates are (0.3028, 0.3334) and classified as cool white. The optical absorbance was found to
be enhanced as the Dy2O3 raised from 0 wt% to 3 wt%. Meanwhile, both the direct and indirect
optical band gaps were decreased consecutively. Thus, this fabricated glass is suggested to be
future solid-state light materials as a white light-emitting diode (WLED) light source. |
