Very recently, NaBiF4 based hosts have evoked considerable interest due to a series of unique advantages. However, the current synthesis methods employed ethylene glycol (EG) as the solvent, which may cause the surrounding-related pollution problems due to the toxicity of EG solvent. Herein, we presented a green, efficient, and environmentally friendly approach to obtain NaBiF4 NPs matrix in the solvent of ethanol substituting the toxic EG. A series of NaBiF4: 0.2Er3+, xTm3+ (x = 0, 0.01, 0.02, 0.04, 0.2) nanoparticles (NPs) were successfully prepared. The obtained NPs exhibit tunable colors from green to red with the increasing of Tm3+ concentration. Furthermore, take the NaBiF4: 0.2Er3+, 0.02Tm3+ compound as an example, the temperature sensing performance was investigated ranging from 298 to 478 K. Not only a high Sa (1.53%) but also superior Sr (1.31%) are simultaneously obtained at 298 K, providing an ideal optical temperature sensor. Meanwhile, to expand the applications, the anti-counterfeiting properties were studied on different substrates. The results show our green synthesis route is feasible and NaBiF4: 0.2Er3+, xTm3+ phosphor has high potential in the optical temperature sensors and anti-counterfeiting applications.

双功能 NaBiF4:用于光学测温和防伪应用的 Er3+、Tm3+ 纳米粒子

最近,由于一系列独特的优势,基于NaBiF 4的宿主引起了相当大的兴趣。然而,目前的合成方法以乙二醇(EG)为溶剂,由于乙二醇溶剂的毒性,可能会导致与周围环境相关的污染问题。在此,我们提出了一种绿色、高效、环保的方法,在乙醇溶剂中替代有毒 EG获得 NaBiF 4 NPs 基质。一系列NaBiF的4:0.2Er 3+,XTM 3+(x = 0时,0.01,0.02,0.04,0.2)成功制备纳米颗粒(NP)。随着Tm 3+浓度的增加,获得的NPs呈现出从绿色到红色可调的颜色。此外,取 NaBiF4 : 0.2Er 3+ , 0.02Tm 3+化合物为例,在298-478 K范围内研究了温度传感性能。不仅高S a (1.53%)而且优越的S r (1.31%)同时在 298 K 下获得,提供了理想的光学温度传感器。同时,为了扩大应用范围,研究了不同基材的防伪性能。结果表明我们的绿色合成路线是可行的,NaBiF 4 : 0.2Er 3+ , xTm 3+荧光粉在光学温度传感器和防伪应用方面具有很高的潜力。
