<正>Silver nanocluster embedded ZnO composite thin film was observed to have an angle-sensitive and fast photovoltaic effect in the angle range from—90°to 90°,its peak value and the polarity varied regularly with the angle of incidence of the 1.064-μm pulsed Nd:YAG laser radiation onto the ZnO surface.Meanwhile,for each photovoltaic signal,its rising time reached ~2 ns with an open-circuit photovoltage of ~2 ns full width at half-maximum.This angle-sensitive fast photovoltaic effect is expected to put this composite film a candidate for angle-sensitive and fast photodetector.
