Water-soluble carbon nanoparticles (CNPs) were fabricated by a facile, one step hydrothermal synthetic route using acid/alkali as additives. These CNPs emit bright photoluminescence (PL) covering the entire visible-near infrared (NIR) spectral range. PL measurements confirmed that the CNPs have up-conversion of PL properties, and that the NIR PL of the CNPs can also be observed by NIR excitation. Control experiments indicated that different additives can strongly affect the PL properties of the CNPs. With a combination of free dispersion in water and attractive PL properties, these CNPs hold promise for applications in nanotechnology.
水溶性碳纳米粒子（CNPs）是通过简便的一步水热合成路线，使用酸/碱作为添加剂制备的。这些 CNPs 发射覆盖整个可见光-近红外（NIR）光谱范围的明亮光致发光（PL）。PL 测量证实，CNPs 具有上转换 PL 特性，并且可以通过近红外激发观察到 CNPs 的近红外 PL。对照实验表明，不同的添加剂可以强烈影响 CNPs 的 PL 特性。这些 CNPs 具有在水中自由分散和吸引力 PL 特性的组合，有望在纳米技术中得到应用。
