The build-up and the decay of persistent photoconductivity (PP) have been measured at room temperature in GaP. The PP effect in our samples is attributed to the existence of defect clusters in the bulk material. Irradiation of the samples with α-particles generates defect clusters and enhances further the PP effect. Persistent photoconductivity at room temperature may have technical applications i.e. photon dose meters and image storage.
