摘要： In a process of forming a capped crystal structure, a precursor solution is heated. The solution comprises a mixture of zinc (Zn) precursor, selenium (Se) precursor, precursor for a dopant, glutathione (GSH), and water. The dopant comprises a transition metal (M). The molar ratio of Zn:Se in the solution may be about 10:3 to about 10:5. The solution is heated for a first period sufficient to allow Zn(M)Se crystal core to form. After the first period of heating, more zinc precursor and GSH are added to the heated solution, and the solution is heated for a second period sufficient to form ZnS crystal shell on the Zn(M)Se crystal core. GSH is added in a sufficient amount to form a GSH layer around the Zn(M)Se/ZnS quantum dot.

摘要： A mixed powder composition is of approximately 25% photoluminescent pigment and 75% binder. The photoluminescent pigment may include chemically doped metal sulfides, alkaline earth metal aluminates or alkaline earth metal silicates that are activated by light and generate a long after glow of light that glows in the darkness for many hours. The photoluminescent pigments are carried by a binder mix such as drywall mix (mineral gypsum) or plaster of Paris (calcium sulfate semihydrate). The powder is sprayable from a bottle with a nozzle onto tree bark, rocks or the ground. As the powder absorbs moisture, it becomes hard to last for months. The photoluminescent pigments in the soft or hardened powder absorbs sunlight or ultraviolet light from a flashlight to emit a long after glow to assist the user in navigating in the dark wilderness.
