Luminescence Characteristics of Nanometer-sized Y2O3:Eu Phosphors |
| 초록 |
Y2O3:Eu phosphor particles with nano-sized and non-aggregation characteristics were prepared by spray pyrolysis using the spray solution containing polymeric precursor and Li2CO3 flux material. Nano-sized Y2O3:Eu phosphor particles had higher brightness than that of the commercial Y2O3:Eu phosphor particles. The Y2O3:Eu phosphor particles had nano-size and non-aggregation characteristics after posttreatment at 1000℃ when the addition amount of Li2CO3 flux was 3 wt.%. The mean size of particles were 300 nm when the amount of flux was 3 wt.%. The prepared phosphor particles had the highest brightness when the content of flux was 5 wt.% and the maximum PL intensity was 125% of the commercial product. The PL intensity of the nano-sized Y2O3:Eu phosphor particles, which were prepared from 3wt.%Li2CO3 containing soln and post-treated at 1000℃ had similar photoluminescence intensity to the micron-sized Y2O3:Eu commercial product. |
