The glass was prepared by hydrolysis and polycondensation of 25 ml of tetraethyl orthosilicate (TEOS) (Aldrich, 98%), 3.42 ml of triethyl phosphate (TEP)(Aldrich, 99%), and 16.53 g of Ca(NO3)2 4H2O (Aldrich, 99%), that is, stoichiometric amounts to obtain anominal composition (mole %) of SiO2 (58), CaO (36), and P2O5 (6). 2 n of HNO3 was used to catalyse theTEOS and TEP hydrolysis, using a molar ratio of H2O/ (TEOS+TEP)=8. Each reactant was consecutivelyadded in 1 h intervals under continuous stirring. Afterwards, the solution was introduced in a hermeticallysealed cylindrical Teflon container where it was allowed to gel at room temperature and then aged at 701C for 3days. The drying was carried out at 1501C for 52 h, having replaced the previous container lid with onefeaturing a hole 1mm in diameter. |

| 玻璃通过25mL四乙氧基硅烷（TEOS）(Aldrich, 98%)、3.42mL三乙基膦 (TEP)(Aldrich, 99%)和16.53 g Ca(NO3)2 4H2O (Aldrich,99%)的水解聚合得到，按化学计量比各成分的摩尔百分比(mole %)为SiO2 (58)、CaO (36)、P2O5 (6)。加入2n的硝酸催化TEOS和TEP水解，其中水与(TEOS+TEP)的摩尔比为8。在搅拌下反应物每隔一小时连续加入。随后将溶液加入到圆柱形四氟乙烯容器并密封，待溶液在室温下成胶后在70度老化三天。随后将密封盖换成一有孔盖（直径1mm）并在150度下干燥52个小时。 |
