Rezumat | |||||||
Absorption, reflection and wavelength modulated reflection spectra were investigated in ZnAl2Se4 crystals. The energy positions of ground and excited states for three excitonic series (А, В and С) were determined. The main parameters of excitons and more precise values of energy intervals V1(Γ7) - C1(Γ6), V2(Γ6) - C1(Γ6) и V3(Γ7) - C1(Γ6) were estimated. Values of splitting due to crystal field and spinorbital interaction were calculated. Effective masses of electrons (m* C1) and holes (m*V1, m*V2, m*V3) were estimated. Reflection spectra contours in excitonic region were calculated using dispersion equations. |
