Super-Delayed Luminescence from Biological Tissues

In this paper we review the experimental results of biophoton delayed luminescence (DL) research and propose a model based on properties of multiphonon energy transfer that explains nearly all known features of DL. Typically, DL is a long (from seconds to hours contrary to the well know luminescence from simple compounds which takes only nanoseconds) decay of intensity after initial light irradiation, and in most cases has very close to hyperbolical law dependence. We proposed the scheme for DL imaging and state that DL has a high diagnostic value, since it differs significantly for damaged tissues.
