Title:
希土類イオンをドープしたアルカリ金属ケイ酸塩発光性ガラス及びその調製方法
Document Type and Number:
Japanese Patent JP2013538170
Kind Code:
A
Abstract:
A preparation method of rare earth ions doped alkali metal silicate luminescent glass is provided. The steps involves: step 1, mixing the source compounds of cerium, terbium and alkali metals and putting the mixture into solvent to get a mixed solution; step 2, impregnating the nanometer micropores glass with the mixed solution obtained in step 1; step 3: calcining the impregnated nanometer micropores glass obtained in step 2 in a reducing atmosphere, cooling to room temperature, then obtaining the cerium and terbium co-doped alkali metal silicate luminescent glass. Besides, the rare earth ions doped alkali metal silicate luminescent glass prepared with aforesaid method is also provided. In the prepared luminescent glass, cerium ions can transmit absorbed energy to terbium ions under the excitation of UV light due to the co-doping of cerium ions. As a result, the said luminescent glass has higher luminous intensity than the glass only doped with terbium.
