Tuning The Wavelength Drift Of Pzt/Pat Composite Structure

The reflection and absorption performance of orderly porous Pb(Zr0.52Ti0.48)O-3 (PZT) on porous alumina template (PAT) structure are investigated, PZT ferroelectric film were deposited on PAT substrate by RF magnetron sputtering process. By controlling the specifications of PZT/PAT nanopores, we could implement the amplitude modulation of absorption edge and reflection. With the decrease of the nanopore size, absorption edge are red shift and the amplitude of the reflection are lower. The wavelength drift between the reflection and absorption has been optimized by changing the thickness of PZT film and structure. This provides an excellent reference to the device of absorption edge/stripe requiring careful tuning.
