A single photoluminescence (PL) band has been detected at room temperature from Pb(ZrxTi1-x)O3 (x = 0 ~ 1.0) surface. The intense and stable PL band covers 475 ± 50 nm (or 2.67 ± 0.25 eV) and the corresponding photo-excitation (PE) band is at 305 ± 45 nm. It is found that changing x causes negligible frequency-shift of the PL and the PE, and no light emission can be detected in Pb absent compounds. 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 and increasing the x values. Possible mechanism of the blue-light emission in Pb(ZrxTi1-x)O3 is discussed.
Keywords:photoemission, oxide
