Second near-infrared window persistent luminescence nanomaterials for in vivo bioimaging

Optical imaging in the second near-infrared(NIR-II,1,000-1,700 nm)window with much reduced tissue scattering plays a crucial role in life sciences due to its high sensitivity and high spatio-temporal resolutions^([1]).Therefore,researchers are committed to developing various types of NIR-II fluorescent probes,such as organic dyes.
