Zero-concentration quenching: a novel Eu 3+ based red phosphor with non-layered crystal structure for white LEDs and NaSrY(MoO 4 ) 3 :Sm 3+ based deep-red LEDs for plant growth

phosphor and the spectral lines were well matched with the phytochrome (Pr) absorption spectrum. The presently investigated phosphor showed potential in a white LED as well as a deep red/orange-red LED for plant growth.
