| Abstract;Ion-exchange reaction of three types of synthetic hydroxyapatites was attempted with Eu3+ and Tb3+ ions for the purpose of preparing phosphors. The ion-exchange reaction was observed when the concentration of Eu3+ and Tb3+ nitrate solutions was less than 10mmol/dm3, however, in the case of higher concentrated solution hydroxyapatites were dissolved partly to yield EuPO4 H2O and TbPO4 H2O. The emission intensity of the ion-exchanged products depended not only on the uptake amount of Eu3+ and Tb3+ ions but also on the Ca/(P+C) ratio of the starting HAps. (author abst.) |
