The Nature of Electronic Excitations in Matter Polymer Blends

The charge carriers (photoelectron and hole) can recombine by different mechanisms and decay channels [42]. 

The Nature of Electronic Excitations in Matter (Polymer Blends) 

A polymer blend is a component of a group of materials in which at least two polymers are blended (i.e., mixed together) to construct a new material with 

In this case, MO represent regions in a molecule where an electron is likely to be found, which are obtained from the overlapping atomic orbitals, and can summarize the following aspects  

M (neutral molecule in ground state) + hv M (molecule in excited state) (24.1)
