PURPOSE:To obtain pure blue luminescence by using a method to form a p-n junction of a zinc chalcogenite crystal. CONSTITUTION:An n-type zinc chalcogenite crystal containing at least one out of selenium and sulfur is arranged inside an open-type reaction container. An organic metal gas having a group I element as a constituent element flows into the reaction container; the group I element is diffused to the zinc chalcogenite crystal; alternatively, Li is diffused to the n-type zinc chalcogenite crystal by using at least one out of a selenide and a sulfide of Li as a diffusion source. Accordingly, the group I element of a comparatively large diffusion coefficient can be diffused to the n-type zinc chalcogenite crystal containing at least one out of selenium and sulfur with good reproducibility and with good mass productivity. Thereby, pure blue luminescence can be obtained. |
