Example Embodiment

[0017] Example 1: Combine Cs(OAc)(0.71mmol), Ag(OAc)(0.5mmol), Sb(OAc) 3 (0.5mmol) was dissolved in octadecene (10mL), oleic acid (2.5mL) and oleylamine (0.66mL). The mixture was stirred at 110°C under vacuum for 45 minutes. Then, the temperature was raised to 180 degrees in a nitrogen environment, and 0.5 mL of trimethylbromosilane was quickly injected. After 30 seconds of reaction, the reactant was placed in a mixture of ice and water and dropped to room temperature. Then the reaction was centrifuged at 8000 rpm for 15 minutes, and then the supernatant was discarded, leaving the orange-red precipitate. This precipitation is Cs 2 AgSbBr 6 Nanocrystalline. Cs 2 AgSbBr 6 Nanocrystals can be dispersed in n-hexane or octane to form colloids.
