Preparation and characterization of acrylic-based luminescent nanomaterials by in-situ emulsifier-free emulsion copolymerization

摘要

Attempts were made to prepare monodispersed organic luminescent nanomaterials by a new procedure, in-situ emulsifier-free microemulsion copolymerization. Highly monodispersed organic luminescent nanomaterials were prepared, and the films were deposited onto solid substrates by spin coating. The diameters of nanomaterials ranged from 20 nm to 100 nm, which were controlled by surfactant. The organic luminescent molecular (VPDPI) was copolymerized with the main monomers and reactive surfactant, and the photoluminescent properties of the films were investigated. The results indicated that the films of organic luminescent nanomaterials were achieved by using the polymerizable luminescent material, and the emission peaks were slightly red shifted with increasing nanoparticle sizes due to exciton confinement.
