Abstract

Spherical InAs nanocrystals of 30-50 nm were hydrothermally synthesized at 120 degrees C, which showed a 100 meV-blueshift of band gap absorption and phonon confinement of optical vibration mode. The study of hydrothermal formation mechanism indicated that crystalline InAs could be obtained in an extended pH range (approximately -0.15 to 14).

摘要

在120摄氏度下通过水热法合成了30 - 50纳米的球形砷化铟纳米晶体，其表现出带隙吸收有100毫电子伏特的蓝移以及光学振动模式的声子限制。水热形成机制的研究表明，在较宽的pH范围（约-0.15至14）内可以获得结晶态的砷化铟。
