Dy 3+ @Mn 4+ co-doped Ca 14 Ga 10−m Al m Zn 6 O 35 far-red emitting phosphors with high brightness and improved luminescence and energy transfer properties for plant growth LED lights

A novel deep red phosphor Ca 14 Ga 10−m Al m Zn 6 O 35 :Dy 3+ ,Mn 4+ (CGAZO:Dy 3+ ,Mn 4+ ) for plant growth LED lighting was successfully synthesized via high-temperature solid-state reaction method and an effective energy transfer from Dy 3+ to Mn 4+ in the CGAZO host had been verified.
