Abstract


A variety of technological applications related to oxide semiconductor-based devices have attracted great interest among the scientific community, leading to an increase in studies of these materials during the last years. Among such materials,  zinc  oxide  (ZnO)  has  applications  in  several  areas,  from  light-emitting  diodes  (LEDs)  to  photovoltaic  devices  in  solar  cells.  Considering  the  physical  and  chemical  properties  conferred  to  these  materials,  the  possibilities  of  application  in  technological  devices  depend  greatly  on  the  synthesis routes employed.  Accordingly, we investigated the morphological modifications in ZnO particles when subjected to sonochemical treatment and the influence of related synthesis method parameters, such as the time and amplitude of sonication. To analyze such effects, four samples were prepared with  different  sonochemical  treatment  conditions:  in  two,  the  amplitude  of  sonication  was  kept  constant  while  varying  the  time  of  sonication,  and  in  the other two, the time was kept constant while varying the amplitude. The analysis of the results obtained indicated that sonochemical treatment led to superficial morphological modifications in ZnO particles. Furthermore, these modifications became more apparent when higher amplitude and longer time of sonication were employed in sample synthesis.
