Influence of water on molecular forms of rhodamine B in dip-coated thin films

Influence of water on molecular forms of rhodamine B in dip-coated thin films Dip-coated thin films including rhodamine B have been prepared using the sol-gel reaction of tetraethyl orthosilicate under relative humidity of 30% and 60%. They have been aged under relative humidity of 20%, 60%, and 95% for 5 days. According to the absorption spectra, just after the preparation of the films and under higher humidity, a larger amount of the dimers (H-and J-types) were formed in the films. Five days after the preparation of the films and aged under higher humidity, the H-dimer increased. On the other hand, the J-dimer increased, regardless of humidity under which the films were aged. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

Dip-coated thin films including rhodamine B have been prepared using the sol-gel reaction of tetraethyl orthosilicate under relative humidity of 30% and 60%. They have been aged under relative humidity of 20%, 60%, and 95% for 5 days. According to the absorption spectra, just after the preparation of the films and under higher humidity, a larger amount of the dimers (H-and J-types) were formed in the films. Five days after the preparation of the films and aged under higher humidity, the H-dimer increased. On the other hand, the J-dimer increased, regardless of humidity under which the films were aged.
