我们提出了一种易于合成的新型稀土(RE)-无离子硼碳氧氮化（BCNO）荧光粉。综述了BCNO荧光粉的制备方法、化学组成、发光性能和发射机理，以及目前BCNO荧光粉的研究进展。以低成本、环保的原料为原料，在低温常压下以液态前体为原料，直接合成了新型BCNO荧光粉。新研制的BCNO荧光粉具有色发射可调、量子效率高、余辉持续时间长等特点。通过改变原料的摩尔比，这些荧光粉的颜色发射可以在几乎整个可见光谱上进行调谐。
We present a facile synthesis of novel, rare-earth (RE)-ion-free boron carbon oxynitride (BCNO) phosphors. The preparation method, chemical composition, luminescent properties and emission mechanisms, as well as current trends in BCNO phosphors are reviewed. The novel BCNO phosphors were synthesized from inexpensive and environmentally friendly raw materials by a straightforward route using liquid precursors at low temperatures under atmospheric pressure. The newly developed BCNO phosphors demonstrated tunable color emission, high quantum efficiency, and long-duration afterglow. The color emission of these phosphors can be tuned across almost the entire visible light spectrum by varying the molar ratios of the raw materials.
