(A)用于测量的氧化锌粉末的透射电子显微镜图像。(B)用He-Cd激光(325 Nm)获得的氧化锌粉末的光致发光光谱。(C)800 nm激发下得到的氧化锌粉末的发射光谱。作为比较，还显示了在325 nm激发下获得的光致发光光谱。插图显示了在800 nm激发下获得的发射光谱的宽波长范围。
(a) The transmission electron microscopy (TEM) image of the ZnO powders used for the measurements. (b) Photoluminescence spectrum of the ZnO powders obtained with a He-Cd laser (325 nm). (c) Emission spectrum of the ZnO powders obtained with excita tion of 800 nm. For comparison, photoluminescence spectrum obtained with excitation of 325 nm is also shown. The inset shows a wide wav elength range of the emission spectrum obtained with excitation of 800 nm.
