How to make phosphorescent glow in the dark powder. Also known as luminescent, photoluminescent or simply glow powder.
Warning: This experiment uses mildly toxic chemicals, wear gloves when handling them. In addition, the combustion reaction must be performed outside or in a fume-hood due to the resulting smoke and gasses.
The procedure is relatively straightforward: 1.875g of aluminum nitrate nonahydrate with 530mg of strontium nitrate, 10.7mg of europium nitrate pentahydrate, 21.9mg of dysprosium nitrate pentahydrate and 30.9mg of boric acid are dissolved in 3mL of distilled water. 3.9g of pure urea is added and shaken until dissolved. The mixture is heated in a 1000watt microwave for 4 minutes. Eventually it'll ignite and combust. The white "ash" is the glow powder.
Can be used in Glow in the Dark Paint if crushed into a powder and mixed with an appropriate clear paint/resin/lacquer/glue.
