The fluorescein-boric acid glass organophosphor has been characterized as a transient photochromic hologram receptor medium in which an excited electronic state gives rise to the holographic grating. It is shown that the holographic signal depends upon dye concentration, sample thickness, and writing laser power. The decay rate of the hologram, after the writing laser is turned off, is determined by the excited state lifetime of 1 sec, while holographic rise times are in the order of 0.1 sec. Diffraction efficiencies are in excess of 0.2% at hologram writing powers of about 500 mW cm(-2). It is thought that this can be improved by choice of either more highly doped systems or pure materials.
荧光素 - 硼酸玻璃有机磷光体已被表征为一种瞬态光致变色全息受体介质，其中激发电子态会产生全息光栅。结果表明，全息信号取决于染料浓度、样品厚度和写入激光功率。写入激光关闭后，全息图的衰减率由1秒的激发态寿命决定，而全息上升时间约为0.1秒。在约500 mW cm(-2)的全息图写入功率下，衍射效率超过0.2%。据认为，通过选择更高掺杂的系统或纯材料可以提高这一效率。
