我们建议使用一种简单而廉价的合成的微米和纳米尺寸的氧化铜（I）颗粒与可变颜色的半导体的大小依赖的光学性质的演示高中学生。通过用葡萄糖还原碱性铜（II）-柠檬酸盐络合物（本尼迪克特试剂）来进行Cu 2 O颗粒的合成。观察并讨论了在不同反应条件下Cu 2 O颗粒的颜色和尺寸的显著变化。建议的演示是非常有用的学生（包括本科生）介绍半导体的尺寸依赖的光学性质和纳米物体的合成原理。
We suggest the use of a simple and cheap synthesis of micro- and nanosized copper(I) oxide particles with variable color as a demonstration of size-dependent optical properties of semiconductors for high school students. The synthesis of Cu2O particles is performed by reducing alkaline copper(II)–citrate complex (Benedict’s reagent) with glucose. Significant color and size changes of Cu2O particles at various reaction conditions are observed and discussed. Proposed demonstration is very useful for introducing students (including undergraduate students) to size-dependent optical properties of semiconductors and principles of synthesis of nanosized objects.
