Reply to the 'Comment on "Spectroscopic properties and location of the Ce3+ energy levels in Y3Al2Ga3O12 and Y3Ga5O12 at ambient and high hydrostatic pressure"' by Y. Wang, M. Głowacki, M. Berkowski, A. Kamińska and A. Suchocki, Phys. Chem. Chem. Phys., 2019, 21, DOI: 10.1039/C8CP06154H.

Abstract

New results presented by Wang et al. showing the temperature dependence of the Y3Ga5O12:Ce3+ energy bandgap have been taken into account in the calculations of the changes of the energy distance between the lowest 5d state of Ce3+ and the edge of the conduction band. Our calculations show that the diminishing of the band gap energy with temperature has a negligible effect on the difference between the energy of the conduction band and the localized states of the 5d configuration of Ce3+, which means that the new experimental results do not undermine the validity of the conclusions of our previous paper.
