The first experimental results for up-conversion photoluminescence excited by using ultra low (~10 W/cm2) intensity non-coherent light in solution of diphenylanthracene blended with platinum octaethyl porphyrin are presented. The crucial advantage of this bi-molecular up-conversion process is the inherent independence from the coherence properties of the excitation light.
