鉛鹵鈣鈦礦的制備為什么總是得不到東西?? 已有1人參與
|
|
In a typical synthesis of CsPbBr 3 , octadecene (15 mL, ODE), OA (1.5 mL), OAm (1.5 mL), and PbBr 2 (0.2 g) were mixed and degased under argon for 1 h. To obtain cubic structure, the reaction temperature was raised up to 180 °C and the system was kept at this temperature for more 20 min. After that, 1 mL of the Cs-precursor was swiftly injected into above system and the reaction was stopped immediately with ice bath. The IPQDs were washed with acetone and toluene via precipitation and redispersed in toluene finally. 在該制備方法中,合成后最后一步使用丙酮和甲苯的洗滌過程是怎么操作的,為什么洗完東西沒有了?也有文獻說用己烷或者乙酸乙酯洗的,到最后東西就洗沒了,貌似全部在溶液中,還離心不下來。剛接觸,不懂o(╥﹏╥)o |
