The reduction of Eu3+to Eu2+in SrB6O10prepared in air by a high-temperature solid state reaction was studied. The luminescent properties of Eu2+in this matrix show f–d broad band emission peaking at about 386 and 432nm at room temperature. A charge compensation mechanism is proposed as a possible explanation. The luminescence of Eu3+with f–f transitions was studied in this sample and reflected that the Eu3+ion occupied a site with non-centro-symmetry. The ESR spectrum was used to detect the existence of Eu2+in the samples.
