Figure 1From: Visible emission from Ce-doped ZnO nanorods grown by hydrothermal method without a post thermal annealing processFE-SEM images of ZnO NRs grown by various ZnO source molarities. ZnO source molarities of (a) 10 mM, (b) 20 mM, (c) 40 mM, (d) 60 mM, (e) 80 mM in the main solution and (f) Variation of the ZnO NR size with variation of source molarities.Back to article page
