Abstract

We report photoluminescence (PL) and chemical properties of nanocrystal phosphors synthesized by low‐temperature wet chemical processing. YAG:Ce^3+^ nanocrystals were synthesized from aluminium isopropoxide, yttrium(III) acetate tetrahydrate and cerium(III) acetate monohydrate in the mixed solvent of 1,4‐butylene glycol and polyethylene glycol (PEG) in an autoclave at 300 °C to discuss roles of PEG surface modification on PL enhancement. We also discuss roles of a lauryl phosphate surface modifier on PL enhancement in two systems of LaPO~4~:Ce^3+^,Tb^3+^ nanocrystals synthesized at 140 °C in the autoclave and ZnS:Mn^2+^ nanocrystals synthesized by a reverse micelle method.
