Low-temperature liquid precursors of crystalline metal oxides assisted by heterogeneous photocatalysis

Abstract

The photocatalytically assisted decomposition of liquid precursors of metal oxides incorporating TiO2 particles enables the preparation of functional layers from the ferroelectric Pb(Zr,Ti)O3 and multiferroic BiFeO3 perovskite systems at temperatures not exceeding 350 ºC. This enables direct deposition on flexible plastic, where the multifunctionality provided by these complex-oxide materials guarantees their potential use in next-generation flexible electronics.

Keywords: complex oxides; ferroelectric thin films; flexible electronics; low-temperature processing; solution methods.
