| 摘 要： | 本文采用热分解法制备了NaYbF4纳米晶.通过TEM图像对NaYbF4纳米晶的尺寸进行表征.根据Beer-Lambert理论建立了NaYbF4纳米晶浓度与其光吸收度间的关系.提出了NaYbF4纳米晶浓度调节方法,利用NaYbF4纳米晶中Yb3+的吸收光谱确定溶液中NaYbF4纳米晶的浓度,并给出了纳米晶浓度调节公式.为了检验这种浓度调节方法,对五批次NaYbF4纳米晶样品的浓度进行调节,发现浓度调节方法非常可靠.并对调整后的浓度进行多次测量,检验此调节方法的误差,最大误差在9;.

| Abstract: | NaYbF 4 nanocrystals were synthesized by thermal decomposition method and the size of nanocrystals were characterized by TEM images.The relationship between the concentration of NaYbF 4 nanocrystals and their absorbances was established by the Beer-Lambert law.A method for adjusting the concentration of NaYbF4 nanocrystals was proposed by the absorption spectrum of Yb^3+ in the NaYbF4 nanocrystal.And then the formula describing concentration adjustment was introduced.Furthermore,the method was tested by five batches of NaYbF4 nanocrystals with different concentrations,which show the method is very credible.And then the concentration of NaYbF4 nanocrystals after adjustment were measured several times to ensure the error of the adjustment method,the maximum error is 9%. |
