合成了一种具有平行2D+2D互穿层和管状沟道的新型蓝色发光锌(II)MOF，它能有效地容纳稀土(III)离子(Ln(3+)=Eu3+、Tb3+或Eu3+/Tb3+的混合物)，从而得到了发光颜色可调的Ln(3+)包裹功能材料，包括红色、绿色和几乎纯的白光。此外，还研究了稀土共掺金属氧化物光纤的热响应发光特性，发现其在液氮温度附近发生了从室温的白色到蓝色的变色转变。
A novel blue-emitting Zn(II) MOF featuring parallel 2D+2D interpenetrated layers and tubelike channels was generated and shown to efficiently accommodate lanthanide(III) cations (Ln(3+) = Eu3+, Tb3+, or a mixture of Eu3+/Tb3+), resulting in the Ln(3+)-encapsulated functional materials with a tunable emission color, including red, green, and nearly pure white light. Furthermore, 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.
