摘要
利用自由基聚合作用制备了Er_(0.5)Eu_(0.5)(TTA)_(3)phen/PMMA温敏漆,并对其光学性质进行了研究。研究结果表明,稀土离子与配体配位成键;Er的掺杂对温敏漆荧光发射具有增益作用;20~70℃范围内,温敏漆具有热猝灭性质;Er的掺杂能够提高温敏漆的相对荧光强度变化率及测温灵敏度。Er_(0.5)Eu_(0.5)(TTA)_(3)phen/PMMA温敏漆作为新型示温材料,在飞行器热密度测量技术等方面具有潜在应用价值。
ErEu(TTA)phen/PMMA temperature sensitive paint(TSP)was synthesized by the radical polymerization and its fluorescence properties were also studied.The results show the rare earth irons were coordinated with ligands successfully,Erhas a gain effect on the fluorescence emission of the TSP and the TSP has the thermal quenching property in the range of 20~70℃.What’s more,the doping of Ercan improve the change rate of the relative fluorescence intensity and the temperature measurement sensitivity of the TSP.Hence,as a new contactless thermal-sensitive material,the ErEu(TTA)phen/PMMA temperature sensitive paint has potential applications in the aircraft thermal density measurement technology and so on.
