Hydrothermal route to InAs semiconductor nanocrystals.
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).
