Abstract
Description
蛍光灯用の市販の三波長形蛍光体の塗料(BaMg2Al16O27:Eu2+(Ce0.67Tb0.33)MgAl11O9(Y0.9Eu0.11)2O3)は、2重量パーセントの樹脂(POLYOX WSR N−750、ダウケミカル社)、0.5gの界面活性剤(TERGINOL NP−6、ダウケミカル社)、10gのトリエタノールアミン、及び0.1gの(商品名SAG275Gで市販の)有機消泡剤を含む純水中に400gの蛍光体を混合することで準備される。塗料は膜厚15nmの層を得るために吹付塗装によって平坦なガラス基板上に堆積され、350℃で5分間加熱された(試料1)。蛍光体層の変換効率は、積分球を備える蛍光光度計で、254nmの紫外光で励起されることで測定された。測定された変換効率はおよそ60%であった。
