摘要
Due to less interference in biological imaging,nanomaterials with second near-infrared(NIR-II)window(950–1700 nm)emission have received tremendous attention.However,no reports on NIR-Ⅱ electrochemiluminescence(ECL)imaging exist because of the lack of high-efficiency NIR-Ⅱ ECL luminophores.Herein,we designed and synthesized a NaYbF4@SiO_(2) core–shell nanoparticle for the first time.
