Resumen
This work presents an analysis of the crystallization process and the influence of laser
surface modification on the crystalline phases and optical responses of Al2O3/glass–ceramic coatings
deposited on a brass substrate. We used a CO2 laser at different irradiation powers to change the
structure of the superficial layer. The photoluminescence response enhanced the resolution of its line
shape as the irradiation power increased. X-ray diffraction patterns exhibit the presence of different
crystalline phases for the samples irradiated
