- Application to the Model of the Solid
All of these observations and conclusions have implications
for the types of impurities in the solids that phosphoresce.
With the Kronig-Penny Model of a solid we can investigate the
depth of the impurity wells relative to that of the other atoms
in the solids. Use Energy Band Creator to create a model solid
that begins to approximate the band and gap structure of phosphorescent
materials. (Because the program operates with a small number
of atoms, you will only be able to obtain a rough idea only.)
- As you manipulate the variables in the program, determine
what variables strongly affect the energy bands and gaps. With
this type of information engineers can create appropriate mixtures
of atoms to design glow-in-the-dark material.
