In this paper, aluminum nitride powder was prepared by carbothermal reduction. Alumina and carbon black powder were used as the starting material to synthesize aluminum nitride powder in a nitrogen atmosphere at 1500~1900°C. The experimental data, SEM photographs and XRD analysis showed that higher temperature was conducive to the increase in conversion ratio of Al2O3, the growth of particles, and improving the degree of crystallization and purity of AlN. But it made the particles’ size larger with poor dispersion.

Eu2+ doped b-SiAlON (z = 1, 3, 4) phosphor were synthesized by carbothermal reduction- nitridation (CRN) using precursors powder as materials. The precursors powder prepared by sol-gel method using the SiO2, AlCl3×6H2O, Eu(NO3)3, ammonia water, carbon powders as starting materials. The CRN reaction proceeded at 1380°C for 6 h in an N2 atmosphere. Eu2+ doped b-SiAlON (z = 1, 3, 4) had high adsorption in the UV-visible spectral region. While z = 1, one bands were observed in the emission spectrum centered at about 425 nm monitored at 282 nm. The excitation bands centered at about 282 nm. While z = 3, one bands were observed in the emission spectrum centered at about 425 nm monitored at 282 nm. The excitation bands centered at about 282 nm. While z = 3, the emission spectra exhibit one bands with maxima at about 419 nm under 280 nm excitation. The excitation bands centered at about 280 nm. While z = 4, the emission spectrum centered at about 419 nm monitored at 280 nm. The excitation bands centered at about 280 nm. In this work, luminescence properties of Eu2+ doped b-SiAlON (z = 1, 3, 4) are independent of z value. It is possible related to the low synthesis temperature.
