Dual-functional nanoparticles with near-infrared (NIR) persistent luminescence and sun-light photocatalytic activity are highly desired for medical diagnosis and environmental protection. Here, we report a facile one-step method for simultaneous enhancement of persistent luminescence and photocatalytic activity of the dual-functional persistent luminescent nanoparticles (PLNPs). The Bi, Cr co-doped ZnGaO PLNPs, which were less than 10 nm in size, were synthesized by an ethylene glycol-assisted hydrothermal method. The persistent luminescence and the photocatalytic activity of the PLNPs were significantly and simultaneously improved additional doping of Bi in ZnGaO:Cr. The prepared dual-functional PLNPs have great potential in pollutant photo-degradation and long-term imaging .

具有近红外（NIR）持久发光和太阳光光催化活性的双功能纳米粒子在医学诊断和环境保护方面具有很高的需求。在此，我们报道了一种简便的一步法，用于同时增强双功能持久发光纳米粒子（PLNPs）的持久发光和光催化活性。通过乙二醇辅助水热法合成了尺寸小于10 nm的Bi、Cr共掺杂ZnGaO PLNPs。通过在ZnGaO:Cr中额外掺杂Bi，PLNPs的持久发光和光催化活性得到了显著且同时的提高。所制备的双功能PLNPs在污染物光降解和长期成像方面具有巨大潜力。
