Abstract
Quantum dots are semiconductor nanoparticles where electrons’ motion is confined within the three physical dimensions of the nanoparticle, such that discretization of energy levels is observed. In this article, quantum dots of Bi2Te3, with sizes around 9 ± 2 nm and energy bandgap around ∼ 2.8 eV, were successfully synthesized by pulsed laser ablation in liquids. Those dots were found to be within the strong confinement regime.
