In this paper, the near infrared luminescence and upconversion luminescence properties of rare earth doped cadmium aluminium silicate ( CAS ), calcium aluminium silicate ( CaAS ) and calcium aluminium germanate ( CaAG ) glasses have been studied. 本论文主要研究新型镉(钙)铝硅酸盐和钙铝锗酸盐玻璃中Er3+、Tm3+和Yb3+的近红外发光和上转换发光性质。
The content of calcium and aluminum residue and low grade bauxite were up to16 % and28 % respectively in preparing belite sulphate aluminium cement. Hydration products of belite sulphate aluminium cement were Aft, hydration calcium silicate gel. 制备贝利特硫铝酸盐水泥的锂渣掺加量可达16%,低品位铝矾土掺量为28%;贝利特硫铝酸盐水泥水化产物为钙矾石和水化硅酸钙凝胶。
