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

, 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 ...

Highly efficient, dual state emission from an organic semiconductor

, 2013
We report highly efficient, simultaneous fluorescence and phosphorescence (74% yield) at room temperature from a single molecule ensemble of (BzP)PB dispersed into a polymer host. The slow phosphorescence (208 ms lifetime) is very efficient (50%) at room

Red Room Temperature Phosphorescence from Lignin

Angewandte Chemie
Abstract Materials with red room‐temperature phosphorescence (RTP) derived from sustainable resources are crucial but rarely reported. Here, we produced red RTP materials from lignin. Lignin was covalently modified with Upy (1‐(6‐isocyanatohexyl)‐3‐(6‐methyl‐4‐oxo‐1,4‐dihydropyrimidin‐2‐yl) urea) to obtain Lig‐Upy.
