How do phosphors work
WebThe meaning of PHOSPHOR is a phosphorescent substance. WebPhosphorescence and thermoluminescence emission from photoconducting impurity activated phosphors have been satisfactorily explained by the storage of electrons, freed from luminescence centres or other atoms of the solid, in metastable energy levels known as electron traps.
