【摘要】 <正> 用溶胶-凝胶法合成无机玻璃、玻璃陶瓷和陶瓷已得到发展。本文报道利用此法低温合成（Ca-Zn）O-Al₂O₃-SiO₂:Eu³⁺,Bi³⁺发光体的研究结果。所用原料为99.99％的Eu₂O₃、99.99％的金属铝、99.999％的金属铋及CaCO₃、ZnCO₃和Li₂CO₃（提纯）。上述原料用HNO₃（GR）溶解。将计算的摩尔比量的Si（OC₂H₅）₄、C₂H₅OH和CH₃COOH以及Ca（NO₃）₂、Al（NO₃）₃、Zn（NO₃）₂、LiNO₃、Bi（NO₃）₃和Eu（NO₃）₃溶液,在一定的pH值下,在75℃水浴中回流数小时,经水解,缩聚成凝胶。制得更多还原

【Abstract】 The luminophors consisted of（Ca-Zn）O-Al₂O₃-SiO₂ were prepared using asol-gel method following by activation by Eu³⁺ and sensitization by Bi.³⁺ The optimum conditions of preparation and chemical compositions of the products are confirmed through powder diffraction and flourescence measurements. The energy transfer from Bi³⁺ to Eu⁺³ is briefly discussed.更多还原
