Abstract

A single band of photoluminescence (PL) has been detected at room temperature from the Pb(ZrxTi1-x)O3(x=0-1.0) surface. The intense and stable PL band covers 475±50 nm (or 2.67 ±0.25eV) wavelengths and the corresponding photoexcitation (PE) band is in the range of 305 ±45 nm. It is found that changing the x value causes a negligible shift of the PL and PE peaks, and the light emission is subject to the Pb presence. The minimal lifetime of the excited photons was found to be 0.03 ms at x=0.5 and the maximum lifetime of 0.60 ms can be achieved by either decreasing or increasing the x values.
