Highly water resistant surface coating by fluoride on long persistent
Sr4Al14O25:Eu2+/Dy3+ phosphor発表情報：Applied Surface Science 巻: 256 号: 8 ページ: 2347-2352キーワード：Phosphor, Fluoride coating, Water resistivity, Sr4Al14O25:Eu2+/Dy3+概要：A novel and efficient method of providing moisture resistance of inorganic particles such as divalent europium activated strontium aluminate phosphors (Sr4Al14O25:Eu2+/Dy3+) was developed by firing the phosphor in the presence of appropriate amount of ammonium fluoride at a temperature of 600–700 C. Scanning electron microscopy, X-ray diffraction, FT-IR, EDAX and Photoluminescence measurements were carried out to characterize the uncoated and coated samples. The pH measurements were carried out for the water resistivity measurements. The phosphor particles became coated with a moistureimpervious thin coating that did not suppress the luminescence of the phosphor and can withstand complete immersion in water for long periods of time, showing very high water resistivity.抄録：A novel and efficient method of providing moisture resistance of inorganic particles such as divalent europium activated strontium aluminate phosphors (Sr4Al14O25:Eu2+/Dy3+) was developed by firing the phosphor in the presence of appropriate amount of ammonium fluoride at a temperature of 600–700 C.
