    摘要: There are provided UV-emitting phosphors, a phosphor blend and a lamp containing same. The blend is comprised of a mixture of a YPO4:Ce phosphor and a LaPO4:Ce phosphor. The YPO4:Ce and LaPO4:Ce phosphors may be surface treated to increase their isoelectric point to enhance lamp stabilization. A third phosphor having an isoelectric point that is at least 3 pH units higher than either of the YPO4:Ce and LaPO4:Ce phosphors also may be added to improve lamp stabilization time. The phosphor blend is lead-free and lamps containing the blend provide equivalent performance to state-of-the-art tanning lamps.
