Abstract:
1. A method for forming a plurality of piezoelectric perovskite lead zirconium titanate (PZT) nanoparticles, the method comprising the steps of: (a) providing a precursor solution comprising a mineraliser, titanium isopropoxide, zirconium n-propoxide, lead acetate trihydrate, acetylacetone, and water, wherein the lead acetate trihydrate, zirconium n-propoxide, and titanium isopropoxide are present in the precursor in a weight ratio of from about 1 to about 2 parts lead acetate trihydrate, from about 0.5 to about 1 parts zirconium n-propoxide, and from about 0.8 to about 1.6 parts titanium isopropoxide; and (b) heating the precursor solution to produce PZT nanoparticles, wherein heating the precursor solution comprises a first heating schedule that includes at least the sequential steps of:
