An organic phosphor has been impregnated in the micropores of anodic oxide film on aluminum to produce a fluorescent aluminum panel.
Aluminum hydroxide was suspended in a solution of sulfosalicylic acid, in which anodically filmed aluminum was immersed at room tem-perature for 24 his. The impregnated film was then heat-treated in the air at 300°C for 10min. The fluorescence intensity was markedly increased by this heat-treatment. The fluores-cence spectrum showed blue to violet band, the emission peak being 395-405 nm. The optimum conditions of obtaining the strongest fluorescence were determined.
