New York University, New York, New York Polycyclic aromatic carcinogens are
generated during various combustion processes and are emitted into the
atmosphere. Because of the widespread presence of these molecules in the
environment, there has been growing concern about their possible effects on
human health (Guerin, 1978).

The decay of luminescence following cessation of excitation is characterized by a
very broad distribution of lifetimes which has been ascribed to the necessity for
electrons to tunnel from localized conduction-band states to the hole. Since the
localization length associated with the tail states decreases as one proceeds
down in energy, tunnelling becomes more difficult as the electron distribution
sinks into the tail. Time-resolved studies of luminescence and ODMR (optically
detected ...

A record of observation of luminescence from ZnS has a long history (Leverenz,
1950; Shionoya, 1966), it dates back to 1 886, when a French chemist Sidot
found phosphorescence from ZnS crystals he grew. Various luminescence
phenomena, which later evolved modern lamps or displays, were discovered
from the end of 19th century to early 20th century. During this period extensive
and systematic studies on luminescent materials were carried out by Lenard. His
works (Lenard ...

ABSTRACT Fluorescence, photoacoustic (PA) and electron paramagnetic
resonance (EPR) studies have been carried out on trivalent terbium doped
thorium oxide compounds at room temperature. These studies have revealed that
terbium ions get partially stabilized in tetravalent state substitutionally replacing
Th4+ ions when the ...

cul'lzeo 00141420 0016*» ocuHae 014H29 oCuHzo The number of studies on
luminescence of metallomesogens in the liquid crystal state is still limited, but
considerable progress is to be expected in the near future. New strategies for the
design of room-temperature mesophases exhibited by metal complexes will
make more types of metallomesogens available for photophysical studies. The
possibility to obtain polarised emission via these systems and the use of these
compounds ...
