Abstract

Abstract We present the synthesis and characterization of halide-terminated colloidal Ge nanoparticles of 2–10 nm with a narrow size distribution, synthesized via a novel reaction route. The nanoparticles are prepared by the disproportionation reaction of metastable Ge(I)X solutions and are obtained in a maximum yield of 79%. Control of the nanoparticle size is achieved by varying the aging time and/or temperature. The halide termination of the nanoparticles is a perfect prerequisite for further surface functionalization but also leads to a high sensitivity of the germanium nanoparticles to water and air.

纳米颗粒合成的新领域：亚稳态GeBr溶液中的锗纳米颗粒

摘要我们介绍了通过一种新的反应路线合成的2–10 nm窄尺寸分布的卤化物封端的胶体锗纳米颗粒的合成和表征。纳米颗粒是通过亚稳态Ge（I）X溶液的歧化反应制备的，并且以79%的最大产率获得。纳米颗粒尺寸的控制是通过改变老化时间和/或温度来实现的。纳米颗粒的卤化物封端是进一步表面功能化的完美先决条件，但也导致锗纳米颗粒对水和空气的高灵敏度。
