The invention discloses glass suitable for a photoelectronic device. The glass is prepared from the following components in percentage by mole: 63-70% of SiO2, 20-30% of PbO, 2-8% of MgO, 0-5% of Cs2O and 0-5% of BaO, wherein the sum of the molar percentages of PbO and SiO2 is greater than 90%; the contents of Cs2O and BaO are not 0 at the same time; and the components do not contain Li2O, Na2O, K2O and Rb2O. The glass provided by the invention has relatively low softening temperature and relatively high secondary electron yield. 本发明公开了一种适用于光电子器件的玻璃，由以下摩尔百分数的组分组成：SiO263-70％，PbO 20-30％，MgO 2-8％，Cs2O 0-5％，BaO 0-5％；其中，PbO和SiO2的摩尔百分数之和大于90％；Cs2O和BaO的含量不同时为0；组分中不含有Li2O、Na2O、K2O和Rb2O。本发明提供的玻璃具有较低的软化温度和较高的二次电子产额。
