Preparation of Bismuthate Fluorescent Glass and Its Luminescent Properties
Abstract: The glass was first prepared by melt-cooling. Five different Bi2O3 / PbO content matrix glasses were analyzed by transmission spectroscopy to obtain the best glass matrix components. The melting temperature, the different melting time and the bismuth varnish glass with different phosphor content were analyzed by photovoltage spectrum and electrochromatogram. The optimum melting temperature was obtained. Optimum melting time and optimum phosphor content. Finally, the best performance of the glass-ceramic and blue light source for simple packaging, composed of light source, measuring its steady-state light flux and color temperature and drive current relationship, and then concluded.
Keywords: Bi2O3 / PbO; melting temperature; melting time; phosphor; glass-ceramic; blue light source
