摘要：

We report on the purification, synthesis, and infrared emission properties of Nd doped PbBr2 and PbI2 crystals. Under optical excitation at similar to 0.8 mu m, characteristic Nd3+ emission lines arising from the F-4(3/2) level were observed. In addition, near infrared emission lines were also observed at similar to 0.97, similar to 1.2, and similar to 1.5 mu m arising from the F-4(5/2),H-2(9/2) states of Nd3+. The emission efficiency at 1.5 mu m was determined to be 74% for Nd:PbBr2 and 64% for Nd:PbI2 with peak emission cross sections in the range of (0.2-0.5)x10(-20) cm(2). These cross sections are comparable to those of Er3+ doped materials employed in optical communications and eye-safe lasers. (c) 2006 American Institute of Physics.
