Abstract:
Although we have a general knowledge of the factors that give corundum its color, the underlying
mechanism for each color variety is still being debated and is a topic of controversy to this day. Green
corundum is one color for which there has yet to be a dedicated study focused on its color mechanism. To
determine the underlying color mechanism and construct energy band models, blue, green, and yellow
synthetic corundum were analyzed using colorimeter, EDXRF, UVVisNIR, and XAS. Energy band gap
calculations for synthetic corundum resulted in values of 4.30 eV for blue, 4.01 eV for green, and 3.62 eV for
yellow. The energy band model for synthetic blue corundum incorporates the Fe3+/Ti4+ mixed acceptor state
while the model for synthetic yellow corundum utilizes Cr3+ neutral state with XANES showing interference
signal from metallic iron and a possibility of Fe3+ neutral state. Synthetic green corundum, on the other hand,
employs both Ni2+ donor states and Fe3+/Fe3+ neutral state to explain its energy band model
