In the paper, by fractional - dimension space model, the relationships between system dimensions and wells width in zno / mgzno quantum well will be studied and the exciton dynamics such as wave functions, radial intensity and bohr radius in zno / mgzno with different well width are studied firstly. secondly, the system dimension, exciton wave functions and absorption spectrum in hexagonal microtube zno film were calculated and simulated, and the confinement of microtube is discussed. then the hexagonal microtube zno films are investigated by capacitance - voltage ( c - v ) measurements and the structure of zno / si were analyzed and modeled
本文利用分數維空間模型，首先研究了zno / mgzno量子阱中系統維度、激子波函數、徑向密度和波爾半徑隨阱寬的變化，從中反映了zno / mgzno量子阱中量子尺寸效應對激子態的影響；其次計算和模擬得到六棱微管zno薄膜的系統維度、激子波函數及吸收譜，討論了微管壁厚對激子的限制情況。Nanoparticles show significant quantum - size effect ( such as energy band discreteness, band gap broadening, blue shift in spectra etc. ) as sizes of particles are smaller than bohr radis of exciton of bulk material with same composition ( for example, cds ’ s bohr radium is 6nm )
當納米粒子的尺寸小於其塊狀材料的激子波爾半徑時（如cds的激子波爾半徑為6nm ） ，能夠表現出明顯的量子尺寸效應（如能帶離散，禁帶變寬，光譜藍移等） 。
