Abstract: A sample was produced by heating the mixture of boric acid, strontium carbonate added europium oxide at 800—1000 ℃ in reductive atmosphere for 4 hours. According to the pattern of X-ray diffraction of the sample, Its phase and mechanism of emission under the ultraviolet excitation of sample are discussed. It was shown that the emission was relative with the content of Sr_(1-x)Eu_xB_4O_7 as well as the impurity of the sample.

Key words: UV-emission, X-ray diffraction, Luminous center Eu2+
