Photosynthetically active radiation (PAR) of lighting sources is a prerequisite to match well with the absorption spectrum of photoreceptors in plants. Light-emitting diodes (LED) or laser diodes (LD) or its combination with phosphor can be used to construct the 660-nm-featured simultaneous emission of both red and blue light for PAR. A variety of rare earth (RE) ion-doped phosphors such as nitride, silicate, sulfide allow a 660-nm-peaked broadband emission with proper composition and preparation, as illustrated by a highly efficient A3MgSi2O8 (AMS, A = Ba, Sr, Ca) phosphor with a dual band emission at both 660 and 430 nm. These phosphors are excitable by sunlight, near ultraviolet (NUV), blue LED, or LD light sources as applied in the forms of particle, film, or transparent ceramics, providing a great potential to construct the artificial lighting sources in the closed, open, or their combined cultivation system with a customized, precise composition of light to achieve high photosynthetic efficiency.
