中文摘要	a new blue-green emitting phosphor ca12al14o33cl2: eu2+, mn2+ has been synthesized by the solid-state reaction technique method under a reductive atmosphere. the x-ray diffraction measurement results indicate that the crystal structure of the phosphor is a single phase of ca12al14o33cl2. the phosphors can be efficiently excited by near ultraviolet (n-uv) light and show a blue emission band at about 450 nm and a green emission band at about 550 nm, which originated from the eu2+ ions and the mn2+ ions. the efficient energy transfer from the eu2+ ions and the mn2+ ions was observed and its mechanism should be a resonant type via a nonradiative dipole-quadrupole interaction. the critical distance between the eu2+ ions and mn2+ ions has been calculated to be about 10.83 angstrom as well. in addition, the temperature dependent photoluminescence of the as-prepared phosphors has been investigated in detail. our results indicate that the developed phosphor may be used as a potential blue-green emitting phosphor for uv-based white leds.
