在可见区或近红外区中发光的发光材料
摘要：
本文描述了发光材料和此种材料在防伪、库存、光生伏打及其他应用中的用途。在一个实施方案中，发光材料具有以下通式：[AaBbXxX’x’X”x”][掺杂剂]，其中A选自第IA族元素中的至少一种；B选自第VA族元素、第IB族元素、第IIB族元素、第IIIB族元素、第IVB族元素和第VB族元素中的至少一种；X、X’和X”独立地选自第VIIB族元素中的至少一种；该掺杂剂包括电子受体和电子供体；a为1－9；b为1－5；x、x’和x”之和为1－9。该发光材料显示具有以下特性的光致发光：(a)至少20％的量子效率；(b)在半宽度处不大于100nm的谱宽；和(c)在近红外区内的峰值发射波长。
摘要（英）：

Luminescent materials and the use of such materials in anti-counterfeiting, inventory, photovoltaic, and other applications are described herein. In one embodiment, a luminescent material has the formula: [AaBbXxX'x'X''x''][dopants], wherein A is selected from at least one of elements of Group IA; B is selected from at least one of elements of Group VA, elements of Group IB, elements of Group IIB, elements of Group IIIB, elements of Group IVB, and elements of Group VB; X, X', and X'' are independently selected from at least one of elements of Group VIIB; the dopants include electron acceptors and electron donors; a is in the range of 1 to 9; b is in the range of 1 to 5; and x, x', and x'' have a sum in the range of 1 to 9. The luminescent material exhibits photoluminescence having: (a) a quantum efficiency of at least 20 percent; (b) a spectral width no greater than 100 nm at Full Width at Half Maximum; and (c) a peak emission wavelength in the near infrared range.
