Popis:	Long persistent nanophosphors of ZnS:Cu+ (Green), ZnO:Mn2+ (Yellow) and CaO:Eu3+ (Red) were prepared through precipitation method. n-heptane was used as a stabilizer to control the particle growth. Green emission of Cu+ in ZnS was found at 506 nm, yellow emission of Mn2+ in ZnO was found at 572 nm, and red emission of Eu3+ in CaO is found at 616 nm. The average growth rate of CaO nanophosphor was 4.72 nm3/s. Adding a stabilizer can stop the particle growth and aggregation. Smaller particle size was obtained by adding n- Heptanes at earlier time.
