The fluorescen properties of polyethylene photoluminescent films connected with injecting to their composition of photoluminophor on the basis of linkings of europium in excitation of UV by radiation of the sun are investigated. For the first time experimental measurement of rates of fluorescent radiation of a photoluminescent film at its exploitation in natural conditions are carried out. The maximum values of fluorescence intensity of films in investigated conditions make near to 8 mW/m2, average day from 0.5 to 2 mW/m2. For the first time the received results have allowed to make a quantitative estimation of fluorescent radiation intensity of photoluminescent films at effective cultivation under them plants in natural conditions. Reproducing of such indices can allow transferring effect studying to controllable laboratory conditions.
