Optically transparent and high‐quality hybrid ZnO nanoparticle and anthracene embedded polyphenylsiloxane (PPS) glass films were spin‐coated on quartz substrates. A strong Förster resonant energy transfer (FRET) process was indicated by the observation of quenching of the ZnO emission and an enhancement of the anthracene emission at room temperature. The efficiency of this energy transfer between ZnO and the S 1 vibronic states of the anthracene molecules can be optimized to exceed 90%.Visible emission from anthracene only, ZnO only, and the ZnO/anthracene hybrid. The anthracene emission is visibly more intense in the presence of ZnO. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
