Abstract

Abstract—

We report upconversion emission multicolor tuning based on mixing two kinds of lanthanide-doped NaYF₄ nanoparticles. The upconversion emission can be continuously and precisely modulated by adjusting the ratio of the nanoparticles with Tm³⁺ and Er³⁺. The chromaticity coordinates of the mixed solution are calculated by upconversion fluorescence spectra, which presents linear variation under different mixing ratio. Moreover, the corresponding relational equations of chromaticity coordinate and concentration ratio are established. In this way, it is easier to achieve the desired chromaticity and provides a quantificational method to realize chrominance adjustment.

掺杂镧系元素的 NaYF4 纳米粒子的上转换发射微调研究

摘要--我们报告了基于两种掺杂镧系元素的 NaYF4 纳米粒子混合的上转换发射多色调谐技术。通过调节纳米粒子与 Tm3+ 和 Er3+ 的比例，可以连续、精确地调制上转换发射。混合溶液的色度坐标是通过上转换荧光光谱计算出来的，在不同的混合比例下呈线性变化。此外，还建立了色度坐标与浓度比的对应关系式。这样，就更容易获得所需的色度，并为实现色度调整提供了量化方法。
