A convenient synthesis of cadmium chalcogenide quantum dots from cadmium acetate and bis(diphenylphosphino)methane monosulfide and –selenide or 1,4-bis(diphenylphosphino)butane monoselenide

GRAPHICAL ABSTRACT

ABSTRACT

The synthesis of both cadmium selenide and cadmium sulfide quantum dots has been effected using a synthetic protocol that avoids the use of volatile, toxic organocadmium reagents and alkyl phosphines.

KEYWORDS:
