报道了过冷水结冰过程的可视化研究。在硅脂/正己烷介质中，用Tb(III)离子、三苯基氧化膦(Tppo)和六氟乙酰丙酮(HFA)配体组成的Tb(HFA)3(Tppo)2被涂覆在铝表面上，用于热敏发光涂料。利用温度相关发射光谱对所制备的Tb(III)传感器进行了表征。利用高速相机观测了过冷水滴的结冰过程。与时间相关的图像清楚地显示了水/冰从最初的物理刺激点到整个液滴的相变。由于结冰过程中潜热的释放，发光强度的降低是Tb(III)离子向HFA配体的热辅助回传能量转移的原因。
Visualization of icing processes of supercooled water is reported. Tb(hfa)3(tppo)2composed of a Tb(III) ion, triphenylphosphine oxide (tppo), and hexafluoroacetylacetonato (hfa) ligands was coated on an aluminum surface using silicon grease/n-hexane medium for temperature-sensitive luminescent paint. The prepared Tb(III)-based sensor was characterized by temperature-dependent emission spectral measurements. The icing processes of a supercooled water droplet were observed using a high-speed camera. The time-dependent images clearly showed the water/ice phase change from an original point of physical stimulation to entire droplet. The emission intensity decrease was responsible for the heat-assisted back energy transfer from Tb(III) ions to hfa ligands due to the latent-heat release during the icing processes.
