ChemInform Abstract: Enhancement of Fluorescent Intensity of a SiO2:Sm Glass by Al Codoping and Local Structure Around Sm by an EXAFS Study.
First published: September 11, 1990
Abstract
It is shown that the emission intensity is significantly increased by Al-codoping of the SiO2:Sm phosphor (preparation by the sol-gel method using Sm(NO3)3, Al(NO3)3, and Si(OEt)4 in EtOH/H2O).
ChemInform Abstract
It is shown that the emission intensity is significantly increased by Al-codoping of the SiO2:Sm phosphor (preparation by the sol-gel method using Sm(NO3)3, Al(NO3)3, and Si(OEt)4 in EtOH/H2O). In the Al-free phosphor, Sm atoms are well dispersed at low Sm content and agglomeration occurs at higher Sm concentration, whereas in the Al-codoped SiO2:Sm glass the Sm atoms are coordinated by Al via Sm-O-Al bondings.
