The solid solubility of aluminum in the sol–gel derived ZnO nanocrystals.

What is it about?

In this study, a sol–gel method was used to synthesize Al-doped ZnO nanocrystals (AZO). For preparation of this highly concentrated sol, zinc acetate concentration was fixed at 2M. UV-visible absorption and photoluminescence spectroscopy were used to evaluate optical properties of the prepared samples. High temperature annealing was employed to evaluate the solid solubility limit of Al ions. XRD and Raman spectroscopy are then used to evaluate the doping process of aluminum in ZnO nanopowders.

Why is it important?

Experimental results have shown that a solid solubility limit of aluminium ions in prepared zinc oxide nanocrystals was achieved. The presence of Alþ3 ions leads to reduction in the size of ZnO nanocrystals.
