钾钠锂含量对钴蓝灯泡玻璃光谱曲线的影响

Effect of Potassium Sodium Lithium Content Proportion on Cobalt Blue Bulb Glass Spectra Curve

在采用稳定性较好的钴离子作为着色离子的基础上，较系统地分析了钾钠的含量比例变化对蓝色玻璃透光曲线的影响，以及氧化锂部分取代氧化钠对蓝色玻璃透光曲线的影响。主波长随离子半径的大的碱含量增加而移向长波方向，随离子半径小的碱离子的增加而移向短波方向。透过这些钴蓝玻璃的灯泡发光钨丝呈现不同的颜色，含大离子半径碱的呈红黄混合色，含小离子半径碱的呈纯正红色。

The cobalt blue bulb glass manufactuerd by soda-lime silicate is substituted for different proportion of potassium, sodium and lithium. The results show that the dominant wavelength of transmission shifts to longer wavelength with increasing of larger radius alkali ion content, similarly, the dominant wavelength of transmission shifts to shorter wavelength with increasing of smaller radius alkali ion content. The luminous tungsten wire of lamp through these cobalt blue glasses appears different colours. The content of larger radius alkali ion appears yellow-red mixed colours and the content of smaller radius alkali ion appears pure red colour.
