激光诱导Y1Ba2Cu3Ox超导靶等离子体发射光谱的研究
Laser-Induced Plasma Spectroscopy of Y-Ba-Cu-O Target
【摘要】 利用ＯＳＭＡ光谱测量方法对Ｎｄ：ＹＡＧ激光烧蚀沉积Ｙ－Ｂａ－Ｃｕ－Ｏ超导薄膜过程中等离子体发射光谱的研究表明，靶表面喷出的粒子中存在着Ｙ、Ｂａ、Ｃｕ原子和离子以及氧化物光谱，其中Ｃｕ离子的光谱很少。
【Abstract】 Photoluminesceence spectroscopy of Nd: YAG laser-induced piasma Plume during plasma-assisted laser deposition of Y-Ba-Cu-O was performed using an optical multichannel analyzer.The spectrun in the range of 320-610nm was measured.It was found that there were not only rich emission of Y,Y+,Ba.Ba+and Cu but also oxide molecule.The causes were also discussed.
