本文将用SILARL的方式制备硫化镉纳米半导体薄膜的实验引入到教学过程中,作为课外实验,可使学生加深理解微观粒子间相互作用力,同时了解科技发展的现状,增加化学学习的兴趣。 In this paper, the experiment of preparing cadmium sulfide nano-semiconductor thin films by SILARL was introduced into the teaching process. As an extra-curricular experiment, students can deepen their understanding of the interaction forces between microscopic particles, understand the current state of science and technology development, and increase the interest in chemistry learning.
