Investigation into Blue Light Emission for Copper-containing Pyrotechnics.

摘要

Pyrotechnic signals typically generate colored light via photonic emission from thermally-excited states of gas-phase metal combustion products. Blue light can be generated in pyrotechnic compositions with the use of copper-containing compounds as a fuel within the formulation. In the presence of chlorine containing compounds within the composition, these pyrotechnics exhibit emission bands in the blue region of the visible spectrum with peaks observed from 435-480 nm.
