Increasing the Solubility Limit for Tetrahedral Aluminium in ZnO:Al Nanorods by Variation in Synthesis Parameters

Figure 6

HR-TEM images of the ZnO:Al nanorods obtained by stirring during a solvothermal treatment of 6 h at 200°C (top) and by a solvothermal treatment of 96 h at 200°C (bottom). The lighter patches are due to beam damage caused by the orientation process of the nanocrystals. The slightly different appearance at the left bottom side of the second crystal is Moiré caused by overlap with another nanocrystal.
