Red-Emitting Cr<sup>3+</sup> on α-Al<sub>2</sub>O<sub>3</sub>:Cr Spheres Obtained in Seconds Using Laser Processing

Cr-doped Al<sub>2</sub>O<sub>3</sub> spheres with strong red emission were produced using a simple laser processing approach with a 50 W continuous CO<sub>2</sub> laser. Structural characterization revealed that the produced spheres were monophasic, comprising the...
