Tape Casting Preparation and Pyroelectric Properties of Stacked Pb(Zr0.97Ti0.03)O3 Thick Films Doped with Nb2O5

Stacked Zr-rich Pb(Zr,Ti)O3 (PZT) thick films doped with different amounts of Nb2O5 have been prepared by the tape casting and stacking processes. The pyroelectric properties of the stacked thick films have been compared with those of single-layer thick films. The full-width of temperature at half maximum of pyroelectric coefficients for the stacked thick films, ΔT, was broadened to 20°C. The maximum pyroelectric coefficient in the stacked thick films was 2.4 ×10-7 C/cm2K. The thermal hysteresis of the pyroelectric coefficient could be partly eliminated by the stacked structure of thick films.
