Gamma ray induced radiation damage in PWO and LSO/LYSO crystals [PDF]

open access: yes, 2010
This paper compares γ-ray induced radiation damage effect in two kinds of heavy crystal scintillators: PWO and LSO/LYSO. Scintillation emission, optical transmission, light output, decay kinetics and light response uniformity were measured for PWO ...

Suppressing molecular motions for enhanced room-temperature phosphorescence of metal-free organic materials [PDF]

open access: yes, 2015
Metal-free organic phosphorescent materials are attractive alternatives to the predominantly used organometallic phosphors but are generally dimmer and are relatively rare, as, without heavy-metal atoms, spin-orbit coupling is less efficient and ...

Luminescence in sulfides : a rich history and a bright future [PDF]

open access: yes, 2010
Sulfide-based luminescent materials have attracted a lot of attention for a wide range of photo-, cathodo- and electroluminescent applications. Upon doping with Ce3+ and Eu2+, the luminescence can be varied over the entire visible region by appropriately

Correlations between electrochemical behaviors and DNA photooxidative properties of non-steroïdal anti-inflammatory drugs and their photoproducts [PDF]

open access: yes, 2012
Alkali-labile lesion to DNA photosensitized, via an electron transfer mechanism, by three non-steroidalanti-inflammatorydrugs (NSAIDs), ketoprofen, tiaprofenic acid and naproxen and their photoproducts during drug photolysis, was investigated using 32P ...

Near‐Infrared Room‐Temperature Phosphorescence from Monocyclic Luminophores

open access: yesAngewandte Chemie International Edition
AbstractCompact luminophores with long emission wavelengths have aroused considerable theoretical and practical interest. Organics with room‐temperature phosphorescence (RTP) are also desirable for their longer lifetimes and larger Stokes shifts than fluorescence.

Iodinated Aluminum(III) Corroles with Long-Lived Triplet Excited States [PDF]

open access: yes, 2011
The first reported iodination of a corrole leads to selective functionalization of the four C–H bonds on one pole of the macrocycle. An aluminum(III) complex of the tetraiodinated corrole, which exhibits red fluorescence, possesses a long-lived triplet ...
