The effect of changing the amount of Sr on the optical characteristics was evaluated. The Photo-luminescence and Mechano-luminescence intensities were greatly increased by reducing the amount of Sr. It seems that the trap state in the crystal changed. From the TL measurement, it was found that the total amount of carriers trapped in the sample were reduced with amount of Sr increasing, but the activation energy of the trap level did not change. So, increase in ML intensity was found to be due to increase in trap level. The activation energy was about 0.55eV for all samples, consistent with previous studies.}, pages = {61--64}, title = {ゲル化燃焼法により作製した希土類添加 アルミン酸ストロンチウム蛍光体の応力発光特性の評価}, volume = {49}, year = {2020}, yomi = {ヨコヤマ, ヒロスミ and サカイ, ケンタロウ and マエダ, コウジ} }
