采用水热法合成多种形貌和尺寸的NaYF4∶Yb3+,Er3+上转换发光材料,探讨螯合剂、敏化剂、激活剂、氟化铵用量及水热时间对目标产物发光性能的影响规律,并通过正交实验优化Yb3+、Er3+共掺杂NaYF4上转换发光纳米材料的合成条件.采用XRD、SEM和荧光光谱对目标产物进行对比分析.结果表明:目标产物为β-NaYF4,在980 nm红外光的激发下,发出明亮的绿光,最强发射峰在542 nm.可通过改变螯合剂的种类来控制生成不同尺寸(纳米级或微米级)和形貌(管状、球形或六棱柱形)的目标产物.所制备的NaYF4∶Yb3+/Er3+上转换发光材料分散性好、荧光强度高,在生物探针及生物成像等领域具有潜在的应用价值.
