A clear relationship between the surface, photocatalytic (PC), and photoluminescent (PL) character of ZnO is observed. With potassium trimethylsilanolate and cobalt(II) acetate we have determined that anionic binding sites occupied by silanolate contribute to 40% of the PL character of the defect emission (500-550 nm).
