1. A method of producing bismuth oxyhalide quantum dots without added heat, comprising:
forming a first solution by dissolving a bismuth salt in an organic solvent;
forming a second solution by dissolving an alkali metal salt in water;
combining the first solution and the second solution to obtain a dual mixture;
combining the dual mixture with an aqueous surfactant solution comprising a surfactant to obtain a final mixture comprising the bismuth oxyhalide quantum dots; and
filtering the final solution to obtain the bismuth oxyhalide quantum dots,
wherein the alkali metal salt is selected from the group consisting of LiI, NaI, KI, RbI, CsI, LiBr, NaBr, KBr, RbBr, CsBr, LiCl, NaCl, KCl, RbCl, and CsCl.
