DIY Glow-in-the-Dark Strontium Aluminate: A Homemade Chemistry Challenge

A blogger attempted to synthesize glow-in-the-dark strontium aluminate (SrAl2O4) at home, a material known for its persistent luminescence. The synthesis involved multiple steps, including the preparation of aluminum nitrate, mixing oxide precursors, and high-temperature calcination. However, due to a lack of appropriate equipment and high-purity reagents, the blogger only achieved short-lived luminescence, falling short of the persistent glow seen in commercial products. This post meticulously details the entire experimental process, including chemical equations, procedures, and challenges encountered, serving as a valuable resource for chemistry enthusiasts.
