    Abstract: A quartz glass lamp vessel 1 or 21 is used in many types of lamps. Sometimes it is expedient to absorb a certain portion of the emission spectrum. In accordance with the prior art this is possible by including rare earth metal oxides in the quartz glass.The solubility of rare earth metal oxides in quartz glass is, however, limited.According to the invention, quartz glass is used which contains an alkali metal oxide and optionally, an alkaline earth metal oxide, in addition to a rare earth metal oxide. The alkali metal oxide increases the solubility of the rare earth metal oxide, so that rare earth metal oxides can be used in larger concentrations. This results in glasses which have a higher degree of absorption, from which lamp vessels can be produced.

    Abstract translation: 在许多类型的灯中使用石英玻璃灯容器1或21。 有时吸收某一部分发射光谱是有利的。 根据现有技术,这可以通过在石英玻璃中包括稀土金属氧化物来实现。 然而,稀土金属氧化物在石英玻璃中的溶解度受到限制。 根据本发明,除了稀土金属氧化物之外,还使用含有碱金属氧化物和任选的碱土金属氧化物的石英玻璃。 碱金属氧化物增加了稀土金属氧化物的溶解度,使得稀土金属氧化物可以以较大的浓度使用。 这导致具有更高吸收程度的玻璃,可以从中制造灯管。
