Zusammenfassung:The invention provides a Bi-Nd-Yb co-doped YAG high-efficiency and wide-spectrum quantum cutting luminescent material. A composition general formula of the luminescent material is Y3Al5O12:xBi, yNd, zYb, wherein x is greater than or equal to 0.5*10 and less than or equal to 1*10, y is greater than or equal to 0.5*10 and less than or equal to 2*10 and z is greater than or equal to 1*10 and less than or equal to 10*10. According to the Bi-Nd-Yb co-doped YAG high-efficiency and wide-spectrum quantum cutting luminescent material provided by the invention, Nd-Yb co-doping belongs to two-step energy transmission and has relatively high energy conversion efficiency; Bi in the luminescent material can be used for effectively expanding an absorption section of Nd through a sensitization effect; sunlight is subjected to broadband absorption so that high-efficiency and wide-spectrum conversion type near-infrared quantum cutting is realized; finally, the sunlight is suf
