図4は、本実施形態に係る紫外線検出物の製造方法を示すフロー図である。図4に示すように、紫外線検出物10を製造するには、まず、ステップS101で、アルミニウム、ストロンチウム、セリウム、ランタン、及びマンガンを含む複数種類の酸化物の粉末を乾式混合する。例えば、酸化アルミニウム粉末、炭酸ストロンチウム粉末、酸化セリウム粉末、及びランタンストロンチウムマンガン酸化物粉末を乾式混合する。
酸化アルミニウム粉末100重量部、炭酸ストロンチウム粉末12重量部、酸化セリウム粉末2.3重量部、及びランタンストロンチウムマンガン酸化物粉末2.3重量部を乾式混合した後、大気中において1500℃で10時間焼成し、焼結体を得た。各酸化物成分のモル濃度はAl2O3が89.4モルパーセント、SrOが7.6モルパーセント、CeO2が1.2モルパーセント、La2O3が0.8モルパーセント、MnO2が1.0モルパーセントである。
実施例1と同様に準備した複合酸化物の粉末100重量部と、ポリメチルアクリレート樹脂の粉末10重量部とを混合し、酢酸エチルを加えて樹脂成分の溶解及び混錬を行いペースト状の紫外線検出物10Bを作製した。
実施例1で作製したペースト状の紫外線検出物10Aと、実施例2で作製したペースト状の紫外線検出物10Bをポリエチレンテレフタレートフィルム上に印刷し、乾燥させた。図5(a)は、参考のために、乾燥させた紫外線検出物10A及び10Bに蛍光灯を照射した様子を示している。
