8-羟基喹啉铝/酞菁/聚苯乙烯平面靶的激光烧蚀特性

Laser Ablation Property of Aluminium 8-hydroxyquinoline/ Phthalocyanine/Polystyrene Planar Target

  • 摘要: 新型高效靶丸结构设计中,内爆靶表面引入某些有机双层薄膜结构可使部分能量沿薄膜的平面传输,使其对称压缩靶丸,实现高效的内爆。文章在PS平面靶表面蒸镀双层功能薄膜,薄膜为8-羟基喹啉铝(Alq3)/酞菁(H2Pc)或苯并咪唑苝(PV)/H2Pc。并对其进行了荧光光谱分析和激光烧蚀实验。研究表明:双层薄膜Alq3/H2Pc和PV/H2Pc产生很强的荧光淬灭;由于该结构横向传输载流子的光电特性,Alq3/H2Pc和PV/H2Pc在很大程度上减弱了PS薄膜的烧蚀,且烧蚀面积分别为无涂层PS薄膜烧蚀面积的8倍和3倍。为新型高效惯性约束聚变靶的设计开发提供了一种新颖的靶丸结构。

     

    Abstract: In the designing of structure for new efficient target, some organic bilayers were induced to the implosion target surface and could transmit the energy along the film surface to achieve the symmetrical compression and the efficient implosion. So the organic bilayer, Alq3/H2Pc or PV/H2Pc, was deposited on PS planar target surface and characterized by photoluminescence spectra and laser ablation. The results show that the Alq3/H2Pc and N, N’-diphenyl glyoxaline-3, 4, 9, 10-perylene tetracarboxylic diimide (PV)/H2Pc bilayer films present strong quenching. As the conducting property of the photo-generators in the lateral direction, the Alq3/H2Pc and PV/H2Pc functional coating could suppress the laser ablation largely and the ablation acreage was as large as 8 times and 3 times of the ablation acreage of PS film without any coating, respectively. So this kind of functional coating on the target provides a new structure in the designing and developing of the new efficient ICF target.
