摘　　要：采用静电纺丝与气相还原氮化相结合的方式制备了Ca_(0.68)Si_9Al_3(ON)_(16):Eu^(2+)带状荧光纤维薄膜。利用FE-SEM、XRD、PL和万能材料试验机等测试方法对材料进行了表征。样品在微观上保持带状纤维结构,宏观上保持薄膜的状态,并具有一定的强度、温度、防水及化学稳定性。样品在1500℃,Eu^(2+)的浓度为0.1下保温4 h后的XRD图谱与Ca_(0.68)Si_9Al_3(ON)_(16)的标准卡片相符合。纤维膜可以被蓝光有效激发,表现为400~700 nm的宽峰发射光谱。将该荧光纤维膜用于盾构盘型滚刀的磨损检测,在主控室既可以实时掌握每把滚刀的磨损程度,又减少了带压和高风险地质段的人工检测,大大节约了投入成本和降低了换刀作业人员的职业风险。Nanobelt Ca（0.68）Si9Al3（ON）（16）： Eu^（2＋） luminescence fibers for wear detection of disc cutter were prepared by a simple process electrospinning combined with gas-reduction method, and then characterized by FE-SEM, XRD, PL, and universal material testing machine. The obtained sample keeps fiber film state in micro and macroscopic level with a certain mechanical strength, temperature, waterproof and chemical stability. XRD patterns of the sample doped with Eu^（2＋） 0.1 nitrided at 1500℃ for 4 h were crystallized well and assigned to Ca（0.68）Si9Al3（ON）（16）in JCPDF card. The fiber film can be effectively excited by blue light, showing a broad emission spectrum in the range from 400 to 700 nm. The luminescent fiber film can be practically assembled onto disc cutters for detection. The wear degree of each cutter can be real-timely monitored in the main control room, which reduces the artificial detection at high pressure and high risk geological section, the investment cost, and the occupational risk of operators.
