Not really. It is the difference between the bottom of the conduction band and top of the valence band in eV. (Generally a signifier of how conductive a material is, eg if the bandgap is really small (or negative if the valence and conduction band overlap), it is a conductor, and if the band gap is large it is an insulator.)

As the material approaches absolute zero, the gap gets larger, and as the electrons travel this larger gap, more and more energy is released, which leads to the shorter wavelength of the light that is emitted. (Orange--->Yellow--->Green)

"There remain four irreducible objections to religious faith: that it wholly misrepresents the origins of man and the cosmos, that because of this original error it manages to combine the maximum servility with the maximum of solipsism, that it is both the result and the cause of dangerous sexual repression, and that it is ultimately grounded on wish-thinking." ~Christopher Hitchens, god is not Great
