Abstract
Thermally stimulated light emission has a variety of applications, ranging from military signaling, rocket tracking, and illuminating devices. This study, reports on the development of novel blue flame compositions with enhanced spectral performance in terms of luminous intensity, and color quality. The light intensity and imprint spectra were measured using digital luxmeter and UV-Vis spectrometer respectively. The main giving of this study is that the light intensity of standard blue flare was increased by 459%; the color quality was also improved by 162%. This was achieved by means of optimizing the ratio of novel color intensifier to color source using aluminum metal fuel. Aluminum was found to maximize the formation of blue color reactive emitting species (CuCl), and to minimize the interfering incandescent emission resulted from MgO. This enhanced performance established the general rule that the color intensifier should be within 10-15Â wt% of the total composition.
