Abstract
The alumina-based compound,
${{12CaO.7Al}}_{2}{{O}}_{3}$
, is a ceramic material with a unique cage-like lattice. Such a structure
has enabled scientists to extract various new characteristics from
this compound, most of which were unknown until quite recently. This
compound has the ability to incorporate different anionic species
and even electrons to the empty space inside its cages, thereby changing
from an insulator into a conductive oxide. The cage walls can also
incorporate different rare earth phosphor elements producing an oxide-based
phosphor. All these characteristics are obtained without a significant
change in the structure of the lattice. It is, therefore, reasonable
to expect that this compound will receive attention as a potential
material for display applications. This review article presents recent
investigations into the application of 12CaO.7Al
$_{2}$
O
$_{3}$
ceramic
in various display devices, the challenges, opportunities and possible
areas of future investigation into the development of this naturally
abundant and environmental friendly material in the field of display.
