1. A method for producing an electro luminescence device, comprising the steps of:

  • providing a compound semiconductor crystal substrate comprising a Group 12 (2B) element and a Group 16 (6B) element in a periodic table;

    disposing a diffusion source on a front surface of the substrate, the diffusion source including an element converting the substrate of a p or n conductor into the opposite n or p conductor;

    forming a pn junction by heat treating and thermally diffusing the diffusion source; and

    forming electrodes on front and rear of the substrate;

    wherein the diffusion source disposed on the front surface of the substrate includes at least one of silicon and carbon, and comprises at least one of Cl, Br, I or alloy thereof.
