We calculated the molecular orbital (MO) energies of α-Al 2 O 3: Cr 3+(ruby) under pressure
non-empirically based on one-electron calculations. The pressure was applied to the …

The crystal-field and Racah parameters of ruby were evaluated based on the first-principles
calculations using the relationship between the ligand-field theory and the molecular orbital …

We fabricated ultrathin metal–oxide–semiconductor (MOS) nanocapacitors using atomic
layer deposition. The capacitors consist of a bilayer of Al 2 O 3 and Y 2 O 3 with a total …

In the presence scenario, dye pollution has become a serious issue in present environment
protection which need extensive attention of the scientific community. Methylene blue (MB) …

Abstract Be 3 Al 2 (SiO 3) 6 including Cr 3+ known as emerald have been widely studied
and utilized for solid-state laser materials. Numerous theoretical investigations on these …

Chromium (Cr)-doped alumina has been applied as bio-probes due to its excellent
properties including high photoluminescence (PL), long lifetime, and unlimited …

Up to recently, it has been difficult to calculate the multiplet energies of compounds using
one-electron approach. Since it only considers one electron and one nuclei, the interaction …

In this work, we engineer 2D/3D hybrid architectures or heterostructures using cost-effective
and scalable layer-by-layer spray deposition methods using 2D MoS2, Ti3C2Tx as building …

The luminescence of Al2O3: Cr3+ is the foundation for advancement of modern laser
technology. Preparation of Al2O3: Cr3+ materials through combustion method is known as …

We investigated the effect of lattice relaxation in the trivalent transition metal ions doped α-Al
2 O 3 crystal (α-Al 2 O 3: TM 3+). The transition metal ions are Sc 3+, Ti 3+, V 3+, Cr 3+, Mn …
