报道了入射角分别为７°、１２°、３０°的ｃ轴取向ＰｒＢａ２Ｃｕ３Ｏ６．３薄膜材料的红外和远红外反射谱．薄膜样品的基底是Ｙ－ＺｒＯ２．在入射角为１２°和７°的反射谱中观察到６个反射峰，分别位于１１０、１６８、２４０、３５０、５７０和６３５ｃｍ－１，它们分别对应于６个ａ－ｂ平面振动的Ｅｕ声子模．在入射角为３０°的反射谱中增加了位于４６５ｃｍ－１的峰，此峰是沿着ｃ轴振动的Ａ２ｕ模．比较３不同厚度薄膜样品的红外光谱，讨论了ＺｒＯ２衬底的反射对样品反射谱的影响 The infrared and far-infrared reflection spectra of c-axis oriented PrBa2Cu3O6.3 thin films with incident angles of 7 °, 12 ° and 30 °, respectively, were reported. The base of the film sample is Y-ZrO2. Six reflection peaks were observed in the reflection spectra with the incident angles of 12 ° and 7 ° at 110, 168, 240, 350, 570 and 635 cm-1, respectively corresponding to the Eu sound of 6 a-b plane vibrations Submodel. A peak at 465 cm-1 was added to the reflection spectrum at an incident angle of 30 °, which is an A2u mode that vibrates along the c-axis. The infrared spectra of three thin films with different thickness were compared, and the influence of the reflection of ZrO2 substrate on the reflection spectra of the samples was discussed
