Persistent spectral hole burning (PSHB) was observed in SrZrO3:Pr3+ based oxides. Holes were observed only in samples which contain protons or deuterons. The speed of hole growth and hole filling for the samples which contain protons were faster than that for the samples which contain deuterons. It was found that the mechanism for this hole burning is a photo-physical process, that is, a light induced tunnelling motion of protons contained in the sample.
