Luminescent materials of lanthanoid complexes hosted in zeolites

Herein we highlight our systematic efforts to develop luminescent hybrid materials by modifying zeolites with lanthanoid complexes, and studies conducted by other groups are also included where it is necessary. Four main approaches were employed to modify zeolites with lanthanoid complexes to produce luminescent hybrid materials: inside functions, closure of the pore opening with an organic sensitizer, inside-outside double functions, and embedding the hybrid materials within matrices. Our emphasis is especially placed on understanding the influence of microenvironments of the void spaces on the luminescence performances of the encapsulated lanthanoid complexes, which has important implications for optimizing the luminescence of the resulting hybrid materials, and potential application as luminescent sensors.
