Compositional engineering of phase-stable and highly efficient deep-red emitting phosphor for advanced plant lighting systems
We synthesized pure olivine phase Na1.06MgP0.94Si0.06O4:Eu deep-red phosphor using straightforward compositional engineering. This phosphor attains a remarkable EQE value of 52%, surpassing the previous record for oxide-based deep-red phosphors, while maintaining a high thermal stability of 85.4% at 150 °C.
