报道了ＹＢａ２Ｃｕ３Ｏ６．３和ＰｒＢａ２Ｃｕ３Ｏ６．３多晶陶瓷ｃ轴取向薄膜样品的红外光谱，在Ｐｒ－Ｂａ２Ｃｕ３Ｏ６．３中观察到９个声子模，对应于５Ｅｕ＋４Ａ２ｕ振动。在ＹＢａ２Ｃｕ３Ｏ６．３材料中观察到１０个声子模，对应于６Ｅｕ＋４Ａ２ｕ振动，其中Ｐｒ的Ｅｕ和Ａ２ｕ模分别为位于１７０ｃｍ－１和１９８ｃｍ－１，Ｙ和Ｅｕ和Ａ２ｕ模分别位于１９１ｃｍ－１和２１７ｃｍ－１．ＰｒＢａ２Ｃｕ３Ｏ６．３和ＹＢａ２Ｃｕ３Ｏ６．３有类似的晶体结构，比较和分析它们的Ｅｕ和Ａ２ｕ模，并根据振动模的频率与质量平方根成反比的规律，认为Ｐｒ在缺氧的四方相ＰｒＢａ２Ｃｕ３Ｏ６．３材料中的价态是正三价
The infrared spectra of c-axis oriented films of YBa2Cu3O6.3 and PrBa2Cu3O6.3 polycrystalline ceramics were reported. Nine phonon modes were observed in Pr-Ba2Cu3O6.3, corresponding to 5Eu + 4A2u vibration. In the YBa2Cu3O6.3 material, 10 phonon modes were observed, corresponding to 6Eu + 4A2u vibration. The Eu and A2u modes of Pr were located at 170cm-1 and 198cm-1, respectively. The Y and Eu and A2u modes were located at 191cm-1 and 217cm -1. PrBa2Cu3O6.3 and YBa2Cu3O6.3 have similar crystal structures, comparing and analyzing their Eu and A2u modes. According to the law that the vibration mode frequency is inversely proportional to the square root of the mass, Pr is considered to be in the anoxic tetragonal PrBa2Cu3O6.3 material The price is three trivalent
