| 中文摘要 | by using metal nitrates as starting materials and citric acid as complexing agent, y3al5o12 (yag) and y3al5o12:eu (1 mol%) (yag:eu) powder phosphors were prepared by a citrate-gel method. the formation process of yag and yag:eu were investigated by means of xrd, tg-dta and ft-ir spectra. the purified crystalline phases of yag and yag:eu were obtained at 800 degreesc. the crystalline yag:eu phosphors showed an orange-red emission with d-5(0)-f-7(1) (591 nm) as the most prominent group, whose intensity was dependent on the ph value of the starting solution, citric acid content and firing temperature. it has been found that the suitable ph and citric acid/metal ratio are 3 and 2 for obtaining the highest emission intensity, respectively. the emission intensity increases steadily with increasing the annealing temperature from 800 to 1200 degreesc, and nearly remains constant after 1200 degreesc. furthermore, great differences were observed for the lifetimes and the charge transfer band of eu3+ in crystalline and amorphous states of yag. |
