Five organic luminophores, 1,2,5‐triphenylpyrrole (TPP) derivatives 3 a–e bearing electron‐withdrawing or electron‐donating groups, have been synthesized by Pd‐catalyzed Suzuki coupling of 1‐phenyl‐2,5‐di(4′‐bromophenyl)pyrrole and para‐substituted phenylboronic acid derivatives. They possess good thermal stabilities with high decomposition temperatures above 310 °C. Investigation of the photophysical...
A blue–green emitting phosphor of the monoclinic Ba2MgSi2O7:Eu2+ was prepared by the combustion‐assisted synthesis method and an efficient bluish‐green emission under from ultraviolet to visible light was observed. The luminescence, crystallinity and particle sizes were investigated by using luminescence spectrometry, X‐ray diffractometry (XRD) and scanning electron microscopy (SEM). The emission...
