摘要：

A new optical absorption band was found at the peak energy of 17 kcm-1 (590 nm) besides the Cl- 2 band (22.5 kcm-1 = 445 nm) in (CnH2n+1 NH3)2MnCl4 (n = 1, 2, 3) irradiated with X-rays at 15 K. The absorption intensity of the new band increases with the X-ray dosage in proportion to that of the Cl- 2 band. The intensity thermally decreases in two steps at temperatures around 50 K and 80 K accompanying the decrease of Cl- 2 band. The absorption band can not be bleached by the 590 nm light (17 kcm-1) at 15 K. The band is assigned to an electron center where an electron is trapped at the ammonium head in the neighborhood of a Cl- 2 vacancy. radiation effect, color center, lattice defect, electron center, layered ionic crystal, two-dimensional crystal, alkylammonium manganese chloride, X-ray irradiation, optical absorption spectrum, thermal bleaching. © 1990, THE PHYSICAL SOCIETY OF JAPAN.
