采用水热法在玻璃衬底上浸渍ZnO晶种，制备出平均粒径为5 nm的ZnO纳米珊瑚礁和纳米纤维。前者和后者的长径比分别确定为100和1000。此外，我们发现，通过增加ZnO纳米线的腔长，紫外激光作用的阈值功率密度可以从纳米珊瑚礁的40 kW/cm（2）显著降低到纳米纤维的8 kW/cm（2）。(C)2004年，美国物理学会。
ZnO nanocoral reefs and nanofibers are synthesized on the glass substrate dip coated with ZnO seed with nanoparticles with an average size of 5 nm under a hydrothermal reaction. The ratios of length to diameter for the former and the latter are determined to be 100 and 1000, respectively. In addition, we found that a threshold power density for UV lasing action could be remarkably reduced from 40 kW/cm(2) for the nanocoral reefs to 8 kW/cm(2) for the nanofibers by increasing the cavity length of ZnO nanowires.
