| Abstract: | The photoelectret characteristics of rare earth ion Sm doped ZnO and ZnO-Pb₃O₄ along with pure ZnO have been studied. The dependence of photoelectret charge on excitation field, photo polarization time, dark depolarization time, intensity and wavelength of illumination have been evaluated. With increase in polarization time, decrease in depolarization time and increase in intensity of illumination, photoelectret charge continues to increase. With increase in field, photoelectret charge first increases and later tends to saturation. No photoelectret effect was observed in nano structured ZnO. |
