Preparing method of zinc/manganese silicate type transparent green-emitting film phosphor under visible wavelength region

摘要

The present invention relates to a high permeability zinc / manganese silicate-based transparent green fluorescent membrane method in the visible region such, if the description in more detail, sub-micron (submicron) after producing a spherical silica having a particle size of less, adding them to the aqueous solution containing the zinc precursor and manganese precursor prepared by firing a zinc / manganese silicate gel Preparation of green fluorescent material is coated by the solution or the zinc / manganese silicate gel to a method of manufacturing a transparent green fluorescence. Manufacturing method as prepared transparent green fluorescent film luminescence properties and dispersion characteristics of the present invention is excellent, because it is excellent in permeability in a visible light region, is suitable for use in the transparent display element. Further, as compared with the conventional vacuum vapor deposition system for producing a thin-film phosphor film with high light emission efficiency and light transmitting as well as in a variety of emission colors can be changed from red to blue, a white display can be realized.
