摘要
Near-infrared (NIR) luminescent lanthanide materials are attractive due to their unique optical and chemical features, such as characteristic sharp luminescence, good photostability and low toxicity. Recently, startling interests for NIR luminescent lanthanide materials have been attracted for their highlighted value in the applications of fiber-optic communications, laser systems, bio-sensing and bio-imaging analysis, etc. NIR luminescent lanthanide materials have been developed as a new class of luminescent optical labels that have become promising alternatives to organic fluorophores and quantum dots for applications in biological assays and medical imaging. These lanthanide luminescent probes offer low autofluorescence background, large Stokes shifts, high resistance to photobleaching, high penetration depth and temporal resolution; such techniques also show potential for improving the selectivity and sensitivity of detecting methods. Different kinds of luminescent materials fabricated by lanthanides (upconversion nanocrystals, mesoporous materials, micelles, lanthanide metal-organic framework, ionic liquids and ionogels) exhibit various NIR luminescent properties, which are attributed to the distinct mechanisms of sensitisation. However, the sensitisation of NIR luminescence remains a real challenge. By summarizing the latest developments in the field of NIR lanthanide luminescent materials in this review, we show distinct design ideas on the NIR lanthanide luminescence, describe various NIR luminescent lanthanide functional materials, and evaluate the features and advantages of near-infrared luminescent materials for the developing trends in the future.
