摘 要：White-light-emitting(WLE) materials have attracted much attention,because of their potential use in display technologies,fluorescent sensors,and other lighting applications.A novel blueemitting Zn(Ⅱ) MOF featuring parallel 2 D+2 D interpenetrated layers and tubelike channels was generated and shown to efficiently accommodate lanthanide(Ⅲ) cations(Ln = Eu,Tb,or a mixture of Eu/Tb),resulting in the Ln-encapsulated functional materials with a tunable emission color,including red,green,and nearly pure white ***,the thermal responsive luminescence was investigated for the lanthanide-codoped MOF to exhibit the chromic transition from white at room temperature to blue around liquid nitrogen temperature.
