Tailoring the emission of Eu based hybrid materials for light-emitting diodes application
Abstract(#br)The rare-earth elements (REEs) derived phosphors play an essential role in light-emitting diodes. Many approaches have been proposed for tailoring the emission color of lamp phosphors by tuning the contents and valances of REEs (such as Ce 3+ , Tb 3+ , Eu 3+ ). As we know, the separation and purifying of REEs from waste phosphors usually requires high cost and complicated operations.
