摘要

采用电调制光谱法研究了玻璃基体中弱约束碲化镉纳米晶体的非线性光学性质。采用物理气相沉积法在厚度为0.8 mm的玻璃样品两侧沉积约10 nm厚的铜电极。在直流高压下记录了样品的透射光谱。观察到吸收带变宽。这很可能是由状态填充引起的。

CdTe nanocrystals studied through in-situ electro-modulation spectroscopy

Non-linear optical properties of weakly confined CdTe nanocrystals in a glass matrix were studied by electro-modulation spectroscopy. Copper electrodes of about 10 nm thick were deposited on both sides of glass samples of thickness 0.8 mm by physical vapor deposition. Optical transmission spectra of the samples were recorded under dc high voltage applied to the electrodes. The absorption band is observed to broaden. This is most likely caused by state filling.
