Design,Preparation and Optical Information Storage of A Cyan Long-persistent Phosphor Ba3Ca2(PO4)3Cl∶Eu2+,Ho3+
摘要
Abstract
Cyan long-persistent luminescent materials are relatively rare.In this work,Ba3Ca2(PO4)3Cl was cho-sen as the host,and a phosphor with excellent cyan afterglow performance was successfully prepared via high-temper-ature solid-state reaction.Its optical information storage behavior was also investigated.The detailed crystal struc-ture parameters of the host were determined through structural refinement,and its density of states was calculated.Under 349 nm excitation,both Eu2+-doped and Eu2+/Ho3+co-doped samples exhibited bright cyan emission,with the emission spectra showing two distinct peaks at 455 nm and 493 nm,corresponding to the characteristic 4f65d1-4f7 transitions of Eu2+at different lattice sites.Compared with the single doped samples,the introduction of Ho3+created new trap levels in the system,significantly enhancing the cyan afterglow performance.Finally,the afterglow mecha-nism and optical information storage behavior of the material were further analyzed,providing important reference for the study and application of cyan long-persistent phosphors.关键词
