Transition metal Mn 4+ doped materials showing very narrow red emission have attracted tremendous interest for compositions based on abundant resources and mild production processes.
The emission spectra of Bi 3+ and Mn 4+ co-doped Ca 3 Al 4 ZnO 10 phosphors match well with the absorption spectra of plant pigments for indoor plant growth lighting.
A novel deep red phosphor Ca14Ga10−mAlmZn6O35:Dy3+,Mn4+(CGAZO:Dy3+,Mn4+) for plant growth LED lighting was successfully synthesizedviahigh-temperature solid-state reaction method and an effective energy transfer from Dy3+to Mn4+in the CGAZO host had been verified.
