In this work, we revisit and show how the structural and photoluminescent properties of the MgGa2O4ceramic compound have been kept unchanged for more than two decades. The obtained results confirm the high quality, radiativeefficiency, 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.

Abstract

In this work, we revisit and show how the structural and photoluminescent properties of the MgGa2O4ceramic compound have been kept unchanged for more than two decades. The obtained results confirm the high quality, radiativeefficiency, 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.
