也不一定非要文献上说的蜡状固体,有时做的是跟文献有所出入的,但是结果是一样的。还有一个可能是里面有油酸,油酸的沸点很高,不是很容易弄干的。

In2O3 Nanocrystals with a Tunable Size in the Range of 4-10 nm: One-Step Synthesis,
Characterization, and Optical Properties

Changlong Chen,†,‡ Dairong Chen,*,† Xiuling Jiao,† and Shaohua Chen‡

J. Phys. Chem. C 2007 10.1021/jp076117s


2.2. Preparation of Indium Oleate.

Into the mixture of 80.0 mL of deionized water and 10.0 mL of anhydrous ethanol was dissolved 9.16 g (30.0 mmol) of sodium oleate at 80 °C
under stirring to give a light yellow solution (A). A 1.96 g (10.0 mmol) portion of InCl3â4H2O was dissolved into the mixture of 10.0 mL of deionized water and 4 mL of anhydrous ethanol to form a colorless solution (B). Solution B was slowly added to solution A to produce the opalescent precipitate. The precipitate was washed with deionized water several times and dried at 60 °C in air for 30 min and then at 75 °C in vacuum for 24 h to give brown stick powders, which are used as the precursor for the following experiments. The indium content in the precursor was analyzed to be 14.6% in the form of In2O3
measured with scorching at 850 °C, which is close to the theoretical value of indium oleate (C54H99InO6).
