Colored glass doped with rare earth elements has a bright, bright color and even changes colors in different light. For example, in the glass of neodymium oxide has this characteristic, it shows purple red in the sunlight, in the fluorescence of purple blue, very beautiful. There is a kind of glass that changes with the intensity of light. People use it as the lens of glasses and the window glass of the house. With this kind of glass as a window, the room can maintain a certain brightness, and no longer need to use curtains to shade, so some people call it "automatic curtain"". It can prevent the UV rays of the sun through the library and Museum Library, installed on the glass, can protect the books and cultural relics from UV damage, in addition to the rare earths, directly adding tungsten and platinum in the glass, can also be made of glass.
