Ọcha Sulfide dabere na fotoluminescent pigmenti

Usoro PS nwere zinc sulfide na sulfide ndị ọzọ na-egbuke egbuke na ntụ ntụ gbara ọchịchịrị. Ugbu a, anyị na-emepụta ụdị 7, na-egbuke egbuke gụnyere akwụkwọ ndụ akwụkwọ ndụ, ọbara ọbara, oroma, ọcha, ọbara ọbara-oroma na rose-acha odo odo. Nke a fotoluminescent pigmenti nwere nnọọ ọcha luminous agba. Enwere ike nweta ụfọdụ agba site na strontium aluminate glow na ntụ ntụ gbara ọchịchịrị.
