Photoluminescence Property of Eu-doped Calcium Aluminium Silicate Glasses林耿,邱建荣摘 要:<正>We report on a simple and novel method to induce Si-related oxygen-deficient defects in CaO-Al2O3-SiO2 glasses by using Al metal instead of part Al2O3.Blue emission is observed from the glass samples.Moreover,the quantities of the oxygen-deficient defects can......
Sound insulation property of Al-Si closed-cell aluminum foam bare board material YU Hai-jun(尉海军)1, YAO Guang-chun(姚广春)1, WANG Xiao-lin(王晓林)2, LI Bing(李 兵)1, YIN Yao(尹 銚)2, LIU Ke(刘 克)2 1. School...). It is found that sound reduction index(R) is small under low frequencies, large under high frequencies and is controlled by different mechanisms. The sound insulation property basically conforms......
