Spectral hole burning quantum efficiency and electron traps in Sm21-ion-doped aluminosilicate glasses

Persistent spectral hole burning (PSHB) in the 7F0-5D0 transition and the electron excitation in the 7F0-4f5d transition of Sm2+ doped in Al2O3-SiO2 glasses were studied from the measurements of hole burning efficiency and the refilling of the burnt hole. The PSHB at low temperature is attributed to the optically activated rearrangement of OH bonds surrounding Sm2+ ions. On the other hand, the PSHB at high temperature is attributed to one-step electron tunneling in the excitation state. The barrier heights for hole filling corresponding to the two mechanisms were determined to be ?0.27 and ?0.90 eV, respectively. Thermal depth of the trap that captures electrons by two-step ionization via the 4f5d state was determined to be ?0.35 eV below the conduction band. A model was proposed for describing the PSHB and electron excitation of Sm2+ doped in Al2O3-SiO2 glasses. In addition, the dependence of hole burning efficiency on the Al2O3 concentration, temperature, and burning wavelength was also studied.application/pdfjournal articl

心房心室関係は孤立性心室逆位に類似しているが,大動脈と肺動脈が交差している極めてまれな症例を経験した。症例は48才女性で胸部X線,CT像より polysplenia, mesocardiaと診断されている。MRI像より心臓の立体モデル化が可能であったが,心房レベルでの詳細は経食道カラー断層エコーにて明瞭に示され,結局上記に加え,atrial situs solitus,azygos continuation of IVC to right sided SVC,atrio-ventricular discordance and ventriculo-arterial concordance with inverted normally related great arteries (isolated atrial noninversion),TAPVC (cardiac type)と診断した。本症の心房心室関係の発生につき,同じく心房心室不一致を持つ孤立性心室逆位や修正大血管転位症,また房室弁交叉症等のこれまでの発生に関する論議をふまえ検討したところいずれの説によっても成立が困難であり,全く新しい心室交差(ventricular crossing)という仮説を呈示した。本仮説は cardiac tubeの心室部が looping以前に左右が入れ替わるという概念で,心房心室不一致の説明,刺激伝導系の説明が容易なこと,またこれまでの通常発生における発生説とは矛盾するところがないことを特徴とする。本仮説を実証することは困難であると思われ,また発生学の常識にいささか反するところがあるが,心房心室不一致や房室弁交叉症に関するこれまでの種々の発生説に比し,きわめて容易に理解されうることからここに敢えて呈示した。journal articl
