Abstract

In their recent article Shoukat Hussain et al. 1 report the results of their density functional theory (DFT) calculations on a series of four Francium-bearing cubic perovskite materials FrDCl3 (D = Ca, Sr, Ge, Sn), discussing their possible applications for smart windows and optoelectronics. In this comment, I highlight the issue of Fr instability that completely undermines the applicability of any Fr-based materials.
