General procedure: In a typical synthesis of Cu40Ag60, 0.45mmol Cu(acac)2 and 0.35 Ag (ac) was mixed with 3mL of OAm, 1 mL of OAc and 11mL of ODE. All synthesis was conducted in a four-necked glass reactor allowing the precise temperature control and inert gas atmosphere under dark conditions. Firstly, the mixture was heated to 60C and kept at this temperature for 10min. Then, the mixture was heated to 180C and kept at this temperature for 30min before it was cooled down to room temperature. After cooling, the resultant reaction mixture was collected with hexane (2mL) and the NPs were separated by centrifugation (8500rpm, 12min) after adding isopropanol (40mL). To further purify the yielded CuAg NPs, the product was centrifuged (8500rpm, 12min) one more time with ethanol (40mL). Finally, the remaining product was dispersed in hexane (10mL) for further use. By using the same recipe and varying metal precursor amounts, two different compositions of CuAg NPs were synthesized. Reductive mixing of 0.3mmol Cu(acac)2 and 0.5 Ag(ac) resulted in Cu30Ag70 NPs and mixing 0.6mmol Cu(acac)2 with 0.4 Ag (ac) led to Cu60Ag40. Synthesis of Ag NPs was conducted with the same recipe without using Cu precursor.

General procedure: The monodisperse CuPd alloy NPs with composition controlwere synthesized by using a modified version of our estab-lished recipe for the CoPd alloy NPs [14]. In a typical synthesis of Cu75Pd25NPs, copper(II) acetylacetonate (0.35 mmol, 90 mg)and palladium(II) acetylacetonate (0.1 mmol, 31 mg) were dis-solved in 3 mL of OAm in a 10 mL of glass vial. In a four-necked glass reactor that allows to study under inert atmosphere,200 mg of MB was dissolved in 3 mL of OAm and 7 mL of 1-octadecene at 80C under magnetic stirring. Next, the metal precursor mixture was quickly injected into the reactor under argon environment. The reaction was then proceed for 1 h before cooled down to room temperature. Then, the colloidal NPs mixture was transferred into two separate centrifuge tubeand acetone/ethanol (v/v = 7/3) was added into the tubes. TheNP product was separated by centrifugation at 8500 rpm for10 min.
