Abstract Tryptophan possesses two sets of emissions, each one of which has one short-lived emission and one long-lived emission. The excitation by π-π absorption at 280 mμ gives u.v. fluorescence and blue phosphorescence under certain conditions, e.g. frozen in an aqueous solution containing glucose or methanol.

Exoelectron Emission as emission of hot electrons
phys. stat. sol. (a), 2004The Exoelectron emission (EEE) and Thermoluminescence (TL) of a KCl thin film were investigated. The experimental results are presented and interpreted from the point of view that the EEE is the emission of hot electrons from the dielectric. This assumption for the difference of the activation energies of EEE (EE) and TL (EL), leads to the expression ...

Congenital hearing impairment has adverse effects on speech and language acquisition as well as on emotional and intellectual development. It has been confirmed that these effects are reduced when recognition and intervention in the case of hearing impairment occur before the age of six months.

In diesem Kapitel untersuchen wir Ubergange der Elektronen zwischen Valenzund Leitungsband und die damit verbundenen Strahlungsprozesse genauer. Besonders interessant erweisen sich stimulierte Emissionsprozesse. Hierbei werden durch Strahlung Elektronenubergange von einem hohen Energieniveau auf ein um die Photonenenergie tiefer liegendes Niveau ...
