Pseudodielectric functions in the visible-deep ultraviolet spectral range of Pb(Zr(sub x)Ti(sub 1-x))O3 (PZT), Pb0.98Nb0.04(Zr0.2Ti0.8)0.96O3, Pb0.91La0.09(Zr0.65Ti0.35)0.98O3 and Pb0.85La0.15Ti0.96O3 films grown on platinized silicon substrates using a sol-gel method and on (0001) sapphire using a radio-frequency sputtering method is measured. The near constancy of the lowest bind-gap energy independent of Zr composition is consistent with the band-structure calculations.
