Аннотация The research included the transmission range in the area of exciton absorption for monocrystals GaSe intercalated by potassium hydroxide in 77-293 K temperature range. It was revealed that relationships of energetic position of exciton maximum Еекс and in the half-width of exciton stripe H of intercalates GaSe have non-monoton nature. The occurrence of high-energetic disposition of the first exciton maximum (n  1) was found in the intercalates, that were investigated compared to non-intercalated GaSe. The change of optical properties of conjunctions of GaSe usage was explained by growth of crystal dielectric constant ε0 due the introduction of intercalates into van der Waals space, that leads to decrease and then to stabilize the size of the exciton.
