We developed a new measuring equipment for Mechano-luminescence (ML) which was emitted by application of vibration stress generated by a piezo actuator.SrAl_2 O_4 emitted broad green light identified from Eu^<2+> in Photoluminescence (PL) and ML. The both intensities of luminescence from BaAl_2 O_4 showed weaker than that from SrAl_2 O_4 caused by the difference in the symmetry of each crystalline structure.}, pages = {63--65}, title = {ユーロピウムを添加した蛍光体の光励起および応力による発光特性の評価}, volume = {44}, year = {2015}, yomi = {フジハラ, コウジロウ and クラモト, トシキ and ヨコヤマ, ヒロスミ and マエダ, コウジ and フジハラ, コウジロウ} }
