Abstract
PURPOSE: To make all luminous particles accessible by calling light even when the thickness of a luminous medium is increased by using a composite luminous medium having the light refractivity corresponding to the wavelength of a calling energy (light) source. CONSTITUTION: The solution of the group 1A and 3A impurity ion compounds on the periodic table, such as sodium bromide, etc., is brought into contact with such a luminous component as barium halide fluoride (chloride) activated by, for example, europium in the matrix of a synthesized solid organic copolymer and the impurity ions are selectively diffused in a luminous matrix by heating the solution after the solvent is removed. In selective diffusion, the mixing ratio of the luminous impurity is determined so that the copolymer can have the light refractivity corresponding to that of the luminous component and the light refractivity of the composite luminous medium composed of the copolymer and luminous component can be balanced by the wavelength of electromagnetic waves (light). Therefore, even when the thickness of the luminous medium is increased, calling light is not absorbed completely in the middle, but can reach all luminous particles.
