采用无表面活性剂溶剂热法合成了NaGd（MoO 4）2：Yb 3 +/Tm 3+纳米晶，并以此为基础实现了多功能上转换发光纳米加热器。采用XRD、SEM、EDS、TEM、HRTEM和SAED等技术对纳米晶的结构、形貌和组成进行了分析。NaGd（MoO 4）2：Yb 3 +/Tm 3+纳米晶在980 nm的光照射下发出蓝色荧光，发射峰位于蓝光和近红外光谱区。基于上转换发光的激发功率依赖性、发光动力学和Yb 3 +/Tm 3+能级，讨论了上转换发光的电子跃迁过程。在980 nm激光照射下，纳米晶表现出高效的光热转换。NaGd（MoO 4）2：Yb 3 +/Tm 3+纳米晶在980 nm激光辐照10 s后，其光热转换斜率效率为17.43 °C/W（Yb 3+掺杂量为10 mol%）和43.64 °C/W（Yb 3+掺杂量为15 mol%）。多功能发光纳米加热器NaGd（MoO 4）2：Yb 3 +/Tm 3+纳米晶体同时具有上转换发光和光热转换能力，有望用于温度自监测光热治疗或其他生物应用。
Multifunctional upconversion luminescent nanoheaters are realized based on NaGd(MoO4)2:Yb3+/Tm3+ nanocrystals synthesized by surfactant-free solvothermal method. The structure, morphology and composition of the nanocrystals are analysed by XRD, SEM, EDS, TEM, HRTEM and SAED techniques. Under 980 nm irradiation, NaGd(MoO4)2:Yb3+/Tm3+ nanocrystals emit blue luminescence with emission peaks located in the blue and near-infrared spectral regions. The electronic transition processes for the upconversion luminescence are discussed based on the excitation power-dependent upconversion luminescence, luminescent dynamics and Yb3+/Tm3+ energy levels. The nanocrystals show efficient photothermal conversion after irradiated by 980 nm laser. The photothermal conversion slope efficiency for NaGd(MoO4)2:Yb3+/Tm3+ nanocrystals irradiated by 980 nm laser for 10 s duration is 17.43 °C/W for 10 mol% Yb3+ doping and 43.64 °C/W for 15 mol% Yb3+ doping. Multifunctional luminescent nanoheater NaGd(MoO4)2:Yb3+/Tm3+ nanocrystals exhibit both upconversion photoluminescence and photothermal conversion capabilities, and are promising candidates for temperature self-monitoring photothermal therapy or other biological applications.
