In this study, a series of Y3Al5O12:Sm3+ luminescent materials with different Sm doping were successfully synthesized by the sol-gel combustion method, and characterized by X-ray diffraction (XRD) and photoluminescence (PL) spectrum to investigate the relationships among structure, luminescent properties and Sm3+ concentration, and the mechanism of self concentration quenching of Sm3+.

In this paper,a series of Dy3+∶Y3Al5O12 luminescent materials with different concentrations were successfully synthesized by the sol-gel combustion method.

Single phase barium hexaferrite nanocrystals were innovatively one-step synthesized via a microwave-assisted sol-gel auto-combustion method using citric acid and ethylene diamine tetraacetic acid as composite chelating agents,and freeze-drying technique was used to remove sols\' moisture that effectively improve the spatial distribution homogeneity of metal ions and oxidant in the gels.

9) nanoparticles with spinel structure were synthesized by sol-gel auto-combustion method and annealed at 200℃、300℃、400℃、500℃、600℃for 4 h in air in order to study the structure and magnetic properties of Mn-Zn-Cu ferrite nanoparticles.
