Effect of rare earth elements on the structural and optical properties of PMMA for possible uses in polymer optical communications

ABSTRACTRare-earth elements (REEs) as Tm+3, Er+3, Yb+3 and Nd+3 have a significant optical photon emission. Therefore, Films of PMMA doped with 5 wt.% of NdCl3, TmCl3, ErCl3 or YbCl3 were prepared ...
