The fabrication and luminescence of Li-doped NC CdS are investigated. Impuritydoped NC have been prepared by sol-gel method in gelatin solution. The luminescence mechanism Li-doped NC CdS are discussed and enhancement of stabilization of luminescence (λ max = 520 nm) by Li and Al co-doping are shows.
