Nanostructured metal oxide thin films with a large specific surface area are
preferable for practical device applications in energy conversion and storage.
Herein, we report instantaneous (milliseconds) photonic synthesis of threedimensional
(3-D) nanostructured metal oxide thin films through the pulsed
photoinitiated pyrolysis of organometallic precursor films made by chemical
solution deposition. High wall-plug efficiency-pulsed photonic irradiation (xenon
flash lamp, pulse width of 1.93 ms, fluence of 7.7 J/cm 2 and frequency of 1.2 Hz)
is used for scalable photonic processing. The photothermal effect of subsequent
pulses rapidly improves the crystalline quality of nanocrystalline metal oxide
thin films in minutes. The following paper highlights pulsed photonic fabrication
of 3-D nanostructured TiO2, Co3O4, and Fe2O3 thin films, exemplifying a
promising new method for the low-cost and high-throughput manufacturing of
nanostructured metal oxide thin films for energy applications.
