Efficient methods for fabricating multifunctional nanoparticles can expand the range of their applications in biomedicine. Therefore, in this study, a mild synthesis method for cubic magnetic up‐conversion nanoparticles (MUCNPs) was explored. The MUCNPs were prepared at 160 °C and exhibited fluorescence when irradiated using a 915 nm wavelength laser along with magnetic properties. The MUCNPs exhibited higher intensity of fluorescence than UCNPs without any addition of magnetic nanoparticles. Moreover, MUNCPs exhibiting fluorescence with three different colors, namely green, yellow, and blue were successfully prepared using different Yb:Er ratios and by replacing Er with Tm; these nanoparticles can be useful for biomedical applications such as in therapies involving single nanosystems.

立方磁性上转换纳米粒子的简便合成

用于制造多功能纳米颗粒的有效方法可以扩展其在生物医学中的应用范围。因此，在这项研究中，探索了一种温和的立方磁性上转换纳米粒子（MUCNPs）合成方法。MUCNPs在160°C下制备，当使用915 nm波长激光照射时，MUCNPs表现出荧光以及磁性。在不添加磁性纳米粒子的情况下，MUCNPs的荧光强度高于UCNPs。此外，使用不同的Yb：Er比并用Tm替代Er可以成功制备出具有绿色，黄色和蓝色三种不同颜色的荧光的MUNCP。这些纳米粒子可用于生物医学应用，例如涉及单个纳米系统的疗法。
