Abstract
- The Cover Feature shows long‐time exposures of sparks obtained from various elements. The background illustrates gold and silver sparks commonly used in firework compositions based on iron, magnalium (Mg/Al), etc. Gray body radiation dominates the color of these sparks. Exotic elements throughout the periodic table have been investigated to break this limit. We report the first color‐changing sparks based on erbium powder that switch between surface combustion (gray body emission) and gas phase combustion (colorful emission). More information can be found in the Full Paper by E. G. Hübner et al. [ABSTRACT FROM AUTHOR]
