摘要：

Lead zirconate titanate (PZT) films were deposited on nesa silica glass substrates by spin coating using a Pb(NO3)(2)-Zr(OC3H7n)(4)-Ti(OC3H7i)(4) solution containing polyvinylpyrrolidone and acetylacetone. The coating solution had stable viscosity for over 1300 h at room temperature. Single-layer PZT films as thick as 0.75 mum could be obtained via single-step spin coating with successive gel film heat treatments at 80, 300, and 700 degreesC. The fired films were optically transparent and crack free, exhibiting P-E hysteresis loops with remanent polarization of 24.6 +/-1.6 muC cm(-2) and coercive field of 95.6 +/-9.8 kV cm(-1).
