Abstract

Pyroelectric SnO2/Fe2O3 nanocomposite films were deposited on glass substrates via spray pyrolysis. Samples with 10, 20, and 40 mol.% Fe were prepared and subjected to X-ray Diffractometry (XRD) and dynamic pyroelectric measurements. XRD analysis confirmed that the samples are nanocomposites with SnO2 and Fe2O3 phases present in the films. As predicted by the Ostwald ripening model, increasing the Fe concentration diminishes the crystallite sizes of the constituent phases. The pyroelectric coefficient pv was found to improve with increasing Fe concentration due to the smaller crystallite size present in the films. The highest observed pv is 2.78 × 105 V/mK at 350oC.
