采用简单的溶液相法在室温下成功合成了不同尺寸的立方氧化亚铜(Cu2O)晶体。用透射电子显微镜、X射线衍射仪和紫外-可见吸收光谱仪对Cu2O晶体的表面形貌、结构性质和光学吸收光谱进行了表征。利用532 nm纳秒激光研究了Cu2O晶体的光限幅特性。实验结果表明，Cu2O晶体的光致发光特性不仅来自于非线性散射，还可能来自于非线性吸收。
Cubic cuprous oxide (Cu2O) crystals with various sizes are successfully synthesized under room temperature by a simple solution-phase route. The surface morphology, structure properties and optical absorption spectrum of Cu2O crystals are characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and UV–visible absorption spectroscopy. The optical limiting (OL) properties of Cu2O crystals are investigated using a nanosecond laser at 532 nm. The experimental results show that the OL properties of Cu2O crystals do not only come from nonlinear scattering, but also might be due to nonlinear absorption.
