Abstract
This paper reports the development of new phosphors using the chemical unit cosubstituting solid solution design strategy.
Highlights
White light emitting diodes exhibit many advantages, such as long lifetime, high luminous efficacy and eco-friendliness over conventional incandescent bulbs or fluorescent lamps.[1]
We report the development of new yellow oxide phosphor via the solid solution design, the emission feature of which is observed to be readily similar to that of YAG:Ce
All samples exhibit patterns similar to pure LuAG, but in the solid solution garnets, the diffraction peaks slightly shift to the lower 2y angles
Summary
White light emitting diodes (wLEDs) exhibit many advantages, such as long lifetime, high luminous efficacy and eco-friendliness over conventional incandescent bulbs or fluorescent lamps.[1]. The introduction of the Mg–Si pair alters the Ce–O bond lengths (four bond lengths increase and four bond lengths decrease), and the as-observed ‘‘sum’’ effect of this structural evolution is the shift of the emission transitions towards lower photon energies (Fig. 8).
