中文摘要	a series of laof:ln(3+) (ln = eu, tb, sm, dy, tm, and/or ho) nanocrystals with good dispersion have been successfully prepared by the hydrothermal method followed a heat-treatment process. under ultraviolet radiation and low-voltage electron beam excitation, the laof:ln(3+) nanocrystals show the characteristic f-f emissions of ln(3+) (ln = eu, tb, sm, dy, tm, or ho) and give red, blue-green, orange, yellow, blue, and green emission, respectively. moreover, there exists simultaneous luminescence of tb3+, eu3+, sm3+, dy3+, tm3+, or ho3+ individually when codoping them in the single-phase laof host (for example, laof:tb3+, eu3+/sm3+; laof:tm3+, dy3+/ho3+; laof:tm3+, ho3+, eu3+ systems), which is beneficial to tune the emission colors. under low-voltage electron beam excitation, a variety of colors can be efficiently adjusted by varying the doping ions and the doping concentration, making these materials have potential applications in field-emission display devices. more importantly, the energy transfer from tm3+ to ho3+ in the laof:tm3+, ho3+ samples under uv excitation was first investigated and has been demonstrated to be a resonant type via a quadrupole-quadrupole mechanism. the critical distance (rtm-ho) is calculated to be 28.4 angstrom. in addition, the laof:tb3+ and laof:tm3+ phosphors exhibit green and blue luminescence with better chromaticity coordinates, color purity, and higher intensity compared with the commercial green phosphor zno:zn and blue phosphor y2sio5:ce3+ to some extent under low-voltage electron beam excitation.
