美国加州圣·巴巴腊0mtek Inc.的R.D.Webb最近获取一项发明一种自发光“涂料”的美国专利(4677008)这种涂料含有在黑暗中发光的微小颗粒物质。此发明克服了一般放射性发光的缺点:即效率低、寿命短、及对环境的危害。一种极小的微球形颗粒是此发明的关键,这种微球与树脂或粘合剂混合就是自发光“涂料”。这种安全又有效的自发光微球是用一种简单
R.D.Webb, 0mtek Inc., St. Babard, Calif., Recently won a U.S. patent (4677008) that invented a self-luminous “coating” which contains minute particulate matter that glows in the dark. This invention overcomes the general disadvantages of radioactive luminescence: low efficiency, short life, and environmental hazards. A tiny bead of microspheres is the key to this invention, and the mixing of such microspheres with resins or binders is a self-luminous “coating”. This safe and effective self-luminous microspheres is a simple one
