XRD shows: when the value of x is between 0.1 and 0.3, the alloying thin film remains the structure of hexagonal wurtzite and the angle of (002) diffraction peak becomes bigger as the value of X increases; The photoluminescence spectra at room temperature shows that the PL spectra of the alloying thin film is composed of the stronger UV emission band and weaker visible band, and UV emission peak will have the blue shift with the content of Mg increasing and the visible emission weakened.

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.
