Notes:
PLZT9/65/35 thick films were prepared from the solution containing PVP360(polyvinylpyrrolidone, with average molecular weight of 360000). With the solutions, the criticalthickness of a single PLZT layer could increase to ~624nm compared with 77nm-thick filmsprepared without PVP360. Furthermore, by adding 20~35% excess of Pb to the precursor solutions,the nano-porous rosette-like structures and a small amount of pyrochlore remnant, which werefound very common in the PVP-modified films, could be eliminated. 35% Pb excess was also foundto initiate liquid-phase sintering, leading to dense and crack-free films. The effect of Pb excess onthe rosette removal and densification behavior of the films was discussed. Moreover, the optical andelectrical properties of the PLZT films with 35% Pb excess were also studied
