Аннотация: As one of the key elements of indoor agriculture, horticultural light sources are developing rapidly towards requiring high energy density, high output power and high stability, which poses a challenge for traditional phosphor conversion devices. To address this, an all-inorganic blue-red dual-emitting light convertor consisting of Ba1.3Sr1.7MgSi2O8:Eu2+,Mn2+ (BSMS) phosphor-in-glass (PiG) plates was prepared to improve the duration lifetime of converted high-power light-emitting diodes (LEDs) and meet the light quality requirements of photosynthesis for indoor agriculture. The obtained samples show an external quantum efficiency of 45.3%, outstanding thermal stability and a specific emission spectrum that highly matches the absorption of chlorophyll and β-carotene. Moreover, a proof-of-concept BSMS-PiG horticultural lamp for application in an indoor plant factory was successfully fabricated based on a ∼370 nm emitting LED chip. The blue-red ratio of its spectrum could be regulated by controlling the thickness of BSMS-PiG and the concentrations of Mn2+ ions within BSMS-PiG. The BSMS-PiG horticultural LEDs were applied to the indoor cultivation of Romaine lettuce. The results indicated that the biomass of Romaine lettuce was 58.21% greater than that of control lettuce samples cultivated under commercial plant lamps. In particular, the content values of total chlorophyll, β-carotene and soluble protein were improved. The BSMS-PiG horticultural LED is a potential candidate to act as a high-power horticultural light source.
