The effect of flux materials on Ba2SiO4:Eu phosphor prepared by spray pyrolysis for continuous sampling |
| 초록 |
Green emitting Ba2SiO4:Eu phosphor particles were synthesized by spray pyrolysis for continuous sampling. Flux materials of chloride type were introduced to enhance PL intensity of Ba2SiO4:Eu phosphor in spray pyrolysis. The effect of flux materials of chloride type on the crystallinity, morphology and PL intensity of Ba2SiO4:Eu phosphor was investigated. PL intensity of Ba2SiO4:Eu phosphor was enhanced by adding flux materials. The dependency of crystallite sizes of Ba2SiO4:Eu phosphor on the amount of flux materials was in agreement with that of PL intensities of that of Ba2SiO4:Eu phosphor. Therefore, the crystallite size is the most important factor in the PL intensity of Ba2SiO4:Eu phosphor and the enlargement of crystallite size is promised to enhance the PL intensity of Ba2SiO4:Eu phosphor. |
