Spectrum Study of Crystal Fe: LiNbO3 in Infrared-Visible-UV

摘要:

文章预览

LiNbO3 is an important crystal which has piezoelectric, ferroelectric and electro-optical functions. It has a wide range of applications. Transmission and reflection spectrum of the LiNbO3 samples on the infrared-visible-ultraviolet light have been measured.The wavelength range is 200nm-2000nm. The transmission and reflection spectrum. The absorption coefficient was calculated by transmission and reflection spectrum. The absorption coefficient of the three samples increased slightly in the beginning of the scanning. Then there was a sudden change upward near 8.4*1014 Hz. Forbidden band Eg was obtained from absorption spectrum. The Eg of the three samples were obtained as 3.996ev,3.407ev and 3.425ev respectively. Forbidden band of LiNbO3 crystals was decreased as the iron doped.
