本発明の一の実施例では、リン光体は、0.01mol%から10mol%の量の活性剤を有する。
20gのY2O3、0.64463gのSc2O3、及び0.2184gのBi2O3が水ベースの懸濁物に加えられる。ゆっくりと22.692gのH3PO4(85%)が加えられる。混合物は室温で24時間攪拌される。溶媒は回転式蒸発器を用いることによって除去される。残った固体は100℃で乾燥される。粉末を乳鉢中で挽きながら0.400gのLiFが加えられる。焼成は、以下の温度プロファイルを用いて実行される。その温度プロファイルは、2時間で800℃まで加熱し、2時間保持し、2時間で1000℃まで加熱し、2時間保持し、最後は4時間欠けて室温まで冷却する。その結果生成された生成物は、メノウ乳鉢を用いて再度挽かれる。その後、600ml水中で140mlのHNO3溶液を用いることによって洗浄される。粉末は、吸引濾過によって分離され、酸を除去するために水で洗浄され、かつ100℃で乾燥される。続いてリン光体は挽かれる。そのリン光体は、挽かれた後に、開いたるつぼ中において900℃で2時間、再度大気中で焼成される。粒子表面から余分なビスマスを除去するため、リン光体は、0.1mol/LのEDTA溶液500mlによって2時間洗浄される。続いてリン光体は濾紙上で回収され、水で洗浄されて、最終的には100℃で乾燥される。
結合剤としてニトロセルロースを有するブチルアセテート中の(Y0.945Sc0.05)PO4:Bi0.005の懸濁物が生成される。リン光体懸濁物は、フローコーティングプロセスによって、内径が5mmの合成石英管(スプラシル(Suprasil)(商標))の内壁に塗布される。リン光体層の厚さは、3mg/cm3のリン光体についての単位面積あたりの重さに対応する。結合剤は、580℃よりも低温で焼かれて除去される。素子は、200から300mbarの圧力のキセノンで満たされ、その後密閉される。酸素による如何なる汚染も慎重に回避されなければならない。アルミニウムホイルからなる2の電極は、素子外壁に対して対角状に結合する。
