The ranking according to a decreasing … WebBi3+and Sb3+with ns2outer electronic configuration can tailor both optical absorption and emission properties for phosphor-converted light emitting diode (pc-LEDs) applications. Therefore, the s-electron dopants (Bi3+and Sb3+) act as both sensitizers and emitters. WebIonic radii follow the same vertical trend as atomic radii; that is, for ions with the same charge, the ionic radius increases going down a column. The reason is the same as for atomic radii: shielding by filled inner shells produces little change in the effective nuclear … Ionization Energies of s- and p-Block Elements.
