Rare earth luminescence has attracted widespread attention for several decades, among which nearinfrared(NIR) light-related up-conversion luminescence and NIR-Ⅱ luminescence are widely used in the biomedical field. The NIR-related luminescence is widely studied due to the excellent performance, such as good biocompatibility, deep tissue penetration depth, low self-fluorescence and minimal light damage to organisms. In this review, we mainly introduce the mechanism for rare earth up-conversion luminescence, NIR-Ⅱ luminescence and conclude their advantages compared with traditional *** excellent priorities provide the basis for NIR-related luminescence bioimaging in vivo. Additionally,we hilglight the scheme for the sensitive detection of substances in organisms and various methods for biological therapy. In spite of the existing research, it is outlined that NIR-related luminescence has great potential to be applied in different aspects, expanding perspectives and future challenges of research in related fields. Based on the current scientific achievements, this review can provide reference for research in the areas mentioned above, expand the research direction and arouse a broad interest in different disciplines to pay attention to rare earth luminescence.

NH_3选择催化还原(NH_3-SCR)是一种优异的NOx脱除技术,当前该技术中使用最广泛的商业催化剂为V_2O_5-WO_3(WO_3)/TiO_2。由于这种催化剂中含有毒的V﹑且具有强的SO_2氧化能力以及高的操作温度窗口(350～400℃)等原因,并不适用于低温条件下使用。因此,发展一种在低温下具有较高活性以及对环境友好的催化剂受到了研究者们的广泛关注。近些年,人们发现Ce基氧化物催化剂具有独特的氧储存和释放以及氧化还原性能,在NH_3-SCR反应中表现出优异的低温催化活性,被认为是SCR反应催化剂的候选者。在此本文详细地阐述了Ce基氧化物催化剂用于低温NH_3-SCR反应过程中的研究进展(活性以及抗硫性能)和存在的缺点,为未来高效Ce基氧化物催化剂的研发提供指导。
