Synthesis of Perovskite Nanocrystal Powders

Check if the same lab product or an alternative is used in the 5 most similar protocols
Perovskite Nanocrystals powder of MA2CuBr4, MA2CuCl4, MA2CuCl3.7Br0.3, and MA2CuCl3.34Br0.66 were synthesized from methanol solutions. The precursors methyl-ammonium chloride (MACl, 99.99%, GreatCell Solar), methyl-ammonium bromide (MABr, 99.99%, GreatCell Solar), CuCl2 (copper chloride, 99% Sigma-Aldrich) and CuBr2 (copper bromide, 99% Sigma-Aldrich). The chemicals were mixed in the desired stoichiometry. For example, to synthesize MA2CuCl3.7Br0.3, 0.134 g of CuCl2, 0.118 g of MACl, and 0.027 g of MABr were mixed in 100 mL of MeOH, stirred for 2 h at 70 ○ C, and left to crystallize for 48 hours in an ice bath (0 ○ C). The powder crystals product was recovered by a rotary evaporator followed by washing the product with diethyl ether and drying at 65 ○ C for 12 h in a vacuum. Finally, the products are stored in an argon-filled glove box. The appearance of perovskite crystal is presented in Figure S1, supporting information.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
