【摘要】：溫敏漆技術(shù)是目前唯一的一種具有非接觸式測(cè)量和全方位測(cè)量雙重優(yōu)點(diǎn)的測(cè)溫技術(shù)。本文中以稀土氧化物(Eu_2O_3、Tb_4O_7、Sm_2O_3、Dy_2O_3、Y_2O_3、Nd_2O_3、ZnO)、甲基丙烯酸(MAA)、水楊酸(HSal)、肉桂酸(HCA)及鄰菲羅啉(Phen)為原料,合成了不同配體的鄰菲羅啉稀土配合物以及鏑摻雜、釔摻雜、釹摻雜和鋅摻雜Eu(MAA)_3Phen配合物。將所獲得的配合物作為探針分子,以聚甲基丙烯酸甲酯(PMMA)為基質(zhì)制備相應(yīng)溫敏漆。采用紅外光譜、紫外-可見吸收光譜、熒光光譜和掃描電鏡對(duì)探針分子的結(jié)構(gòu)、發(fā)光性能、形貌和溫敏漆的溫度猝滅性能進(jìn)行表征。結(jié)果表明,稀土離子均與主配體配位,Phen參與了配位,摻雜的不同金屬離子未改變Eu(MAA)_3Phen結(jié)構(gòu)。探針分子均出現(xiàn)較強(qiáng)π-π*躍遷吸收。在分別以Eu~(3+)、Tb~(3+)、Sm~(3+)為中心稀土離子,MAA、HSal、HCA為主配體,Phen為第二配體的9種三元配合物探針分子中,Eu(MAA)_3Phen具有最好的發(fā)光性能及溫敏性能。釔對(duì)Eu(MAA)_3Phen的發(fā)光具有敏化作用,鏑、釹和鋅對(duì)Eu(MAA)_3Phen的發(fā)光具有不同程度的猝滅作用。所制備的溫敏漆在25~65℃溫度范圍內(nèi)均具有良好的溫度猝滅性能。所獲得的探針分子具有不同的形貌。綜合分析得出,以釔摻雜Eu(MAA)_3Phen為探針分子的溫敏漆具有更好的應(yīng)用前景。
[Abstract]:Temperature-sensitive lacquer technology is the only one with the advantages of non-contact measurement and omni-directional measurement. In this paper, rare earth oxides (Eu_2O_3,Tb_4O_7,Sm_2O_3,Dy_2O_3,Y_2O_3,Nd_2O_3,ZnO), (MAA), salicylic acid (HSal), cinnamic acid (HCA) and o-phenanthroline (Phen) were used as raw materials to synthesize the rare earth complexes of o-phenanthroline and dysprosium doped, neodymium doped and zinc-doped Eu (MAA) _ 3Phen complexes. The obtained complex was used as probe molecule and poly-methyl methacrylate (PMMA) was used as the substrate to prepare the corresponding temperature sensitive paint. Infrared spectra, UV-Vis absorption spectra, fluorescence spectra and scanning electron microscopy were used to characterize the structure, luminescence, morphology and temperature quenching properties of the probe molecules. The results showed that the rare earth ions were all coordinated with the main ligand, Phen was involved in the coordination, and the structure of Eu (MAA) _ 3Phen was not changed by doping different metal ions. All the probe molecules exhibit strong 蟺-蟺 * transition absorption. Among the nine ternary complex probes with Eu~ (3), Tb~ (3), Sm~ (3) as the center, MAA,HSal,HCA as the main ligand and Phen as the second ligand, Eu (MAA) _ 3Phen has the best luminescence and temperature sensitivity. Yttrium sensitizes the luminescence of Eu (MAA) _ 3Phen, and dysprosium, neodymium and zinc have different quenching effects on the luminescence of Eu (MAA) _ 3Phen. The prepared temperature sensitive paint has good temperature quenching property in the temperature range of 25 鈩，
