Abstract
The luminescence of the complex formed by manganous chloride with 4-ethyl-3-methylpyridine hydrochloride and of the complex formed by manganous chloride with 2-ethylpiperidine hydrochloride h.as been investigated. These compounds exhibit green and yellow-green luminescence whose spectral distribution may be represented by a funciton close to the Gaussian distribution, which makes it possible to calculate the characteristic constants a and m for any temperature. From the excitation and reflectance spectra the exsistence of the excitation states 4T 1g, 4T 2g8 and 4A 1g, 4E g was found. The character of luminescence is determined by the tetrahedral structure of the [MnCl4]2 - ion in the solid state. It was found that the phenomenon of luminescence is due to the 4T 2g → 6 A1 transition.
