| 中文摘要 | the long lasting phosphorescence (llp) phenomenon in mn2+-doped ceramic based on zno-al2o3-sio2 (zasm) is observed. after irradiation by a uvp standard mercury lamp peaking at 254 nm with a power of 0.6 mw/cm(2) for 15 min, the ceramic sample emits a bright green light peaking at 519 nm, which can be seen in the dark even 15 h after the removal of uvp standard mercury lamp by the naked eyes whose limit of light perception is 0.32 mcd/m(2). the initial afterglow intensity reaches about 1900 mcd/m(2), and the color coordinate (x, y) is (0.2280, 0.5767) at about 10 s after stopping irradiation. the thermoluminescence (tl) spectra show that there are at least three kinds of trap centers with different trap levels while electron spin resonance (esr) spectra indicate that there are electron- and hole-trapping centers induced after irradiation by a uvp standard mercury lamp. based on these measurements, the llp is considered to be due to the recombination of electrons and holes at trapping centers with different levels, which are firstly thermally released back to mn2+ and then give rise to the bright green llp at room temperature. |
