Several types of glass and plastic materials were shown to exhibit intense photoluminescence when irradiated with UV. Water or phosphate buffered saline (PBS) contained within vessels of the respective materials when irradiated, also demonstrated relatively long-lived luminescence. A significant percentage (30%) of cultured mammalian cells were killed when exposed to UV-irradiated glass beads. The nature of the luminescence of water or PBS, or whether this or the photoluminescence of glass is directly responsible for cell toxicity, is unknown. However, we call attention to this phenomenon as a potential complicating factor in photobiological studies.
几种玻璃和塑料材料在紫外线照射下会发出强烈的光致发光。当照射各自材料容器中的水或磷酸盐缓冲盐水（PBS）时，也会表现出相对持久的发光。当暴露于紫外线照射的玻璃珠时，相当比例（30%）的培养哺乳动物细胞被杀死。水或PBS发光的性质，以及这种发光或玻璃的光致发光是否直接导致细胞毒性尚不清楚。然而，我们提请注意这一现象，它可能是光生物学研究中的一个复杂因素。
