Li(Sc,M)Si2O6∶Cr3+(M=Ga3+/Lu3+/Y3+/Gd3+)的近红外发光性能
Near-infrared Luminescence of Li(Sc,M)Si2 O6∶Cr3+(M = Ga3+/Lu3+/Y3+/Gd3+)
摘要
Abstract
Near-infrared phosphor-converted light-emitting diodes(NIR pc-LEDs)are expected to be the next-gen-eration NIR light sources,which have the advantages of small size,broad bandwidth,and easy tuning of emission peaks.The key for NIR pc-LEDs is to develop highly efficient broadband NIR phosphors that can be effectively excit-ed by blue light.LiScSi2O6∶Cr3+can be excited by blue light and emits NIR light peaked at 845 nm with a broad band-width of 156 nm and an internal quantum efficiency of 64.4%.Herein,Sc3+ is replaced by M ions(M = Ga3+,Lu3+,Y3+,Gd3+)to regulate the NIR luminescence.The introduction of M ions is easy to form heterogeneous phases or un-dergo phase transformation,thus reducing the NIR luminescence of the titled material.The regulation processes are analyzed based on the crystal structure.关键词
