Site occupancy and photoluminescence properties of a novel deep-red-emitting phosphor NaMgGdTeO6:Mn4+ with perovskite structure for w-LEDs

A series of novel red-emitting NaMgGdTeO6:Mn4+ phosphors synthesized via the high-temperature solid-state reaction method have been investigated, which shows the potential application in UV/blue-pumped white light-emitting diodes.326
