摘要：
We report a plant growth lamp utilizing near-ultraviolet light-emitting diode and A(3)MgSi(2)O(8):Eu2+, Mn2+ (A=Ca, Sr, Ba) phosphors with emission spectra consisting of blue and red bands, which conform well to the action spectra of plants and absorption spectra of chlorophylls. Either peak positions of the two bands or intensity ratio of red to blue band can be tailored by tuning the compositions of the cations. Eu-Mn energy transfer in the phosphors was investigated on the bases of photoluminescence, life decay time, and microstructure. This functional solid-state lighting provides a simple, compact, and efficient solution to illuminator for plant cultivation. (C) 2008 American Institute of Physics.
