 note = {P(論文), 放射線照射されていない固体において, 表面へのガス吸着に起因する熱ルミネッセンスを生じる現象(吸着ルミネッセンス)について調べた。BaSO_4 : Eu粉末への水, エタノール, アセトン等の蒸気の吸着によるルミネッセンスは, Eu^<3+>の励起準位からの緩和発光による615nmの線スペクトルと可視全域に広がる帯スペクトルとから成り, 線スペクトルと帯スペクトルの強度比および帯スペクトルの形状は吸着種に依存して異なる。吸着ルミネッセンスにおよぼす履歴効果と, ルミネッセンススペクトルの温度依存, 雰囲気変化に対する過渡応答等について計測した。, The thermoluminescence of unirradiated solids originated from adsorption of gases (adsorption thermoluminescence) has been examined. The luminescence of BaSO_4 : Eu phosphors results from the adsorption of water, ethanol and acetone vapor. The luminescence has a main line spectrum at 615nm and a sub band spectrum ranging from 400 to 700nm. The main line spectrum corresponds to the de-exitation emission of Eu^<3+>, whereas the sub band spectrum does not appear in normal thermoluminescence. The ratio of the intensity of the main and sub spectrum and/or the structure of the band spectrum are dependent on adspecies. Sustained emission is observed when the vapor of these organic solvents are introduced into synthesized air. These observations suggest that the measurement of adsoption luminescence spectrum may realize the analysis of environmental gases. The effect of the sample history on adsorption thermoluminescence, the temperature dependence of the luminescence spectrum and the transient response of the luminescence to alterations in the gas environment are measured. It may be concluded that the adsorption thermoluminescence which appeared for samples stored in the atmosphere results from the recombination radiation between electrons trapped into the surface states originated from chemisorbed water and free holes released from the surface states originated from chemisorbed oxygen.},
