| Abstract: | Two-dimensional(2D) TiO2 nanogrids were replicated from butterfly wing scales as bio-templates by vacuum evaporation and high temperature calcination method,and then characterized by SEM,EDS and TEM.The adsorption properties of the nanogrids to CdTe quantum dots were analyzed.The results show that 2D-TiO2 nanogrids could be prepared successfully using the method.The bio-templates could be completely removed by high temperature calcination,and well-covered CdTe quantum dots on TiO2 nanogrids were formed.The ... |
