摘要： The silyl phosphine compound of the present invention is represented by the formula (1) and has an arsenic content of not more than 1 ppm. The process for producing a silyl phosphine compound of the present invention is a process comprising mixing a basic compound, a silylating agent and phosphine to obtain a solution containing a silyl phosphine compound, removing a solvent from the solution to obtain a concentrated solution of a silyl phosphine compound, and distilling the concentrated solution, wherein an arsenic content in the phosphine is adjusted to not more than 1 ppm by volume in terms of arsine. The process for producing InP quantum dots of the present invention uses, as a phosphorus source, a silyl phosphine compound represented by the formula (1) and having an arsenic content of not more than 1 ppm by mass.
(For definition of R, see the specification.)-

摘要： The invention provides a light-emitting composite film layer, a backlight module, and a display device. The light-emitting composite film layer includes a quantum dot film layer and a diffusion film layer. The diffusion film layer is disposed on at least one surface of the quantum dot film layer. Quantum dots and light diffusion particles are dispersed in the quantum dot film layer. The quantum dots include green light and red light quantum dots, and light diffusion particles are dispersed in the diffusion film layer. The invention makes blue light divergent, makes the blue light reach same brightness viewing angles as red light and green light, and reduces or even eliminates color cast.
