Studying the Infrared Spectroscopy of the Pure Aluminum Oxide and Europium Doped Aluminum Oxide Compounds

Abstract

The study of transparent oxides (TCO) is of great scientific importance due to its wide scientific applications. Therefore, our study came to some of the physical properties of the compounds of both pure aluminum oxide and europium doped aluminum oxide. By measuring the infrared spectrum of pure aluminum oxide, it is found that there are five vibratory frequencies, namely:(3523 – 3457 – 2450 – 1647 – 719) cm- 1 and five vibratory frequencies for europium doped aluminum oxide at 0.003%:(3518 – 3435 – 3175 – 2385 – 1580) cm- 1 The study showed that the absorbance values, the absorption coefficient, the refractive index and the optical length were in the europium doped sample by 0.003% greater than that of the pure aluminum oxide compound and are respectively: α=34.96 cm-1  n=5.68.Keywords: aluminum oxide - Infrared spectrum - absorption coefficient - refractive index - Optical conductivityDOI: 10.7176/CMR/10-5-01Publication date:May 31st 2020
