Abstract

Classical blue-green excitable CaS:Eu

phosphor with desired red emission was synthesized by microwave (MW) field with a high frequency of 2.45 GHz. The phosphors can be excited in a wavelength range from 410 nm to 580 nm. In particular

the phosphors exhibit a 476 nm excitable 654 nm peaked red emission. The effect of MW power on material crystal structure

particle size

morphology and luminescent properties was researched by varying the firing power of MW. It has been established that the dielectric property of materials affects MW heating process. MW power supply acts as an effective indicator to predict the viability of dielectric property of materials due to the MW energy. The results show that the variation of MW power can not affect the crystal field of Eu

in lattice matrix. It is obvious that the phase purity

particle size

and morphology are different with the variation of applied MW power. The phase purity CaS:Eu

phosphor with smaller particle size can be obtained in the MW power range of 1.0 kW to 1.1 kW. However

the samples contain CaO impurity phase and the particles are severely agglomerated in the MW power range of 1.2 kW to 1.3 kW. In conclusion

a maximum PL intensity at 1.1 kW of MW power is acquired for the obtained purer host phase.
