PROBLEM TO BE SOLVED : To provide a method for preparing a luminescence material containing no rare earth element having maximum absorption wavelength of 410 nano (nm) to 470 nano (nm) and a method of conducting luminescence of white photoluminescence by application thereof. SOLUTION : The invention relates especially to a method for preparing manganese-doped zinc selenide nanoparticle emitting an orange color light with wavelength between 500 nano (nm) to 700 nano (nm) by exciting with receiving light and a method of conducting luminescence of warm white photoluminescence by application of the manganese-doped zinc selenide nanoparticle emitting an orange color light with wavelength between 500 nano (nm) to 700 nano (nm).
