    Abstract: At least two luminescent materials are intermingled within a security feature. The materials are selected from among a larger set of luminescent materials each having a different individual exponential decay characteristic (decay constant and initial amplitude response to the degree of excitation) for photo-luminescent emission from the respective material following excitation. The ratio of the decay constants for any two materials is greater than or equal to about 1.5. The selected materials are mixed in one of a plurality of predetermined ratios. The combined emissions from the intermingled materials appear, to an unsophisticated measuring device, to have a single exponential decay constant. Based on measurements for the decay of the combined emissions following excitation, estimates of the individual decay constants and associated initial emission amplitudes allow decoding of the particular combination of materials and/or their ratios to validate the security feature, authenticating the article.

    Abstract translation: 至少两种发光材料混合在安全特征内。 这些材料选自对于来自激发后的各材料的光致发光的各种具有不同的指数衰减特性（衰减常数和激发程度的初始振幅响应）的较大组的发光材料。 任何两种材料的衰变常数之比大于或等于约1.5。 所选择的材料以多个预定比率之一混合。 来自混合材料的组合发射出现在不复杂的测量装置上，具有单个指数衰减常数。 基于对激发后的组合发射的衰减的测量，单个衰减常数和相关联的初始发射幅度的估计允许对材料的特定组合和/或其比率进行解码以验证安全特征，认证该文章。
