A third alternative along the horizontal axis is to use spectral class. Its luminosity (intrinsic brightness or absolute magnitude). 9.9.these energy levels are screened by the 5s and 5p states which make them insensitive to the host matrix where the er ions are inserted.

Default view initially all levels and transitions are shown on the plot. In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. The size comparison panel above shows the relative size and color of such a star compared to our sun. 9.9.these energy levels are screened by the 5s and 5p states which make them insensitive to the host matrix where the er ions are inserted.
