Yb3+和Er3+共掺杂的NaY(WO4)2纳米晶的制备与发光性能
Abstract:
采用水热法制备出NaY(WO4)Yb3+,Er3+纳米发光粉。通过X射线衍射、扫描电子显微镜表征了制备的发光粉样品；研究了不同Yb/Er摩尔比对发光强度的影响。结果表明Yb3+和Er3+共掺杂的NaY(WO4)2属于四方晶系，其粒径在30nm左右，且分散均匀。当Yb/Er摩尔比为41时，NaY(WO4)Yb3+,Er3+发光粉样品的发射峰强度达到了最大值。用980nm激光对其进行激发，在室温下观察到了410、524、553和656nm的发射峰，分别对应于2H9/2→4I15/2，2H11/2→4I15/2，4S3/2→4I15/2和4F9/2→4I15/2的跃迁。根据激发功率与发光强度的关系得出410、524、553和656nm发射峰均为双光子过程。
