The luminecsence of ZnSCdS-Cu phosphors of various CdS consentration (0-40%) is under investigation. The luminescence was exited by hydrogen atoms during adsorbtion of thermal energy during adsorbtion and impact recombination-heterogeneous chemiluminenscence(HCL) are discussed. The monotone lowering of the conductivity zone bottom level with respect to the valence zone ceiling (from 3,7 eV to 3,2 eV) with increasing CdS concentration (from 0 - 40%). HCL intensity with respect to CdS (from 3,7 eV to 3,2 eV)- concentration ($E_g$)grows rapidly. The dependence of HCL intensity on the forbidden zone width can be explained by the action of electron - hole pairs multiquontum generation mechanism.
