Synthesis of Nanoparticle of ZnO for Drug Delivery.

Nanocrystalline ZnO powders were synthesized using ultrasonic atomization technique. Effect of precursor concentration (0.1, 0.35, 0.5 and 0.75 M), pyrolysis temperature (973, 1073 and 1273 K) and aerosol carriers (Air/Oxygen) on ultrasonically atomized nanocrystalline ZnO powders was studied. The powders were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), selective area electron diffraction (SAED), absorption spectroscopy (UV-vis) and photoluminescence (PL). It was observed from XRD and TEM that the powder consisted of nanocrystallites with sizes less than 20 nm. The nanocrystalline ZnO powder showed that crystallite sizes were observed to increase with an increase in the concentration of solution and pyrolysis temperature.
