Vanadyl phthalocyanine ( vopc ) films prepared by vacuum deposition were annealed under magnetic field . uv - visible absorption results showed that the films annealed under magnetic field showed a q - band red - shift . x - ray diffraction study ( xpj ) ) indicated enhancement in diffraction intensity and shift of peak position 分析表明酞菁氧钒分子uv - vis吸收谱q带峰值发生较大的红移； xrd测试中衍射峰强度明显增强，峰位变化，但峰宽变化不大；原子力显微镜( afm )分析发现晶粒大小无明显变化。
The results show that the differences between the two composites are very large . although the micrograph of the ni nano - wire and the co nano - wire are nearly the same , as the metal composition increased , the absorption band - edge of the ni / aao composite is small red - shifted ( 13 run ) , however , the absorption band - edge of the co / aao composite is strongly red - shifted ( 80 nm ) . meanwhile , the ni / aao and co / aao composite exhibit the optical features of the semiconductor with indirect and direct band gap respectively 或no组份比的增加， ni / aao吸收边的红移量仅约13nln ，而co / aao的吸收边红移量却超过了80lun ，分析发现ni / aao复合体系具有间接带隙半导体的光学特征，而co从ao复合结构则具有直接带隙半导体的光学特征; 5 .实验研究了a创aao纳米有序阵列复合结构的光吸收特性，在其光吸收谱上出现了较强的ag表面等离子体振荡吸收峰，随ag沉积量的减少，吸收峰位发生红移，且逐渐展宽
The size of the zno nanocrystal grain was so little that the quantum confinement effect should be considered . that makes the band gap wide . atom transfer rate is affected by the substrate temperature , and the average size of the zno nano crystal grain increases with the increasing substrate temperature resulting in the red shift of pl emission position and the narrowness of pl fwhm 低温生长的氧化锌晶粒小，考虑到量子限制效应，禁带宽较大；衬底温度影响吸附原子迁移能力，随着温度升高，晶粒的尺寸增大，分布变的均匀，因而发光峰位随着衬底温度的升高而红移，发光的半高宽变小。
