Problems solved by technology

However, for MOX materials, there are only a small amount of reports on the preparation method of ferric oxychloride in the prior art, specifically in the case of argon as a protective gas, Fe 2 o 3 and anhydrous FeCl 3 The powder is fully mixed with a molar ratio of 4:3, then vacuumed to seal it in a quartz tube, and baked at 380°C for one week
The reaction time of this method is too long, and it needs to be carried out under vacuum conditions, which requires high equipment, increases costs, and the obtained product is a three-dimensional structure, not a two-dimensional layered structure, which has a certain impact on its application range

Description

technical field [0001] The invention relates to the technical field of inorganic semiconductor materials, in particular to a nanosheet of ytterbium oxychloride and its preparation method and application. Background technique [0002] In recent years, two-dimensional layered materials have attracted the attention of researchers all over the world due to their great application prospects in next-generation electronic and optoelectronic devices such as field effect transistors, memories, and photodetectors. Although more than 5,600 materials are defined as layered materials, the current research on two-dimensional layered materials is mainly focused on other "star" materials such as graphene, transition metal sulfides, black phosphorus, and boron nitride. However, these "star" materials still face problems such as uncontrollable preparation, instability, and poor electrical properties, which limit their application in real life. [0003] Recently, two-dimensional oxygen-contai...
