Structural and photoluminescent properties of the MgGa_(2)O_(4):Co^(2+)ceramic compound revisited after two decades

In this work,we revisit and show how the structural and photoluminescent properties of the MgGa_(2)O_(4) ceramic compound have been kept unchanged for more than two decades.The obtained results confirm the high quality,radiative efficiency,and chemical stability of this ceramic,proving that the material is a strong candidate to be used in optical device applications with relatively long useful life.
