[求助] 铅卤钙钛矿的制备为什么总是得不到东西？？已有1人参与

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.
在该制备方法中，合成后最后一步使用丙酮和甲苯的洗涤过程是怎么操作的，为什么洗完东西没有了？也有文献说用己烷或者乙酸乙酯洗的，到最后东西就洗没了，貌似全部在溶液中，还离心不下来。刚接触，不懂o(╥﹏╥)o
