回复应该就是荧光物质了我找了两份材料,也不太清楚对不对 1。什么化学物质涂在墙上用光照就会反射亮光——荧光物质。(来自百度知道) http://zhidao。baidu。com/question/35693940。html?si=4 2。这个是从外国网站上找的,是紫外线下显形的,我没全看懂=。= 里面也提到了“荧光剂”Inks visible under ultraviolet light Some inks glow faintly (fluoresce) when under an ultraviolet lamp。 This is a property of many substances。 There are commercially available inks that glow very brightly when illuminated using a black light or UV light。 Invisible inks with fluorescent properties can be obtained in a variety of colors and even have formulations for non-porous surfaces so they can be used on glass, plastics, etc。。 ■laundry detergents that contain optical brighteners。 Other inks work in a near opposite way by absorbing ultraviolet light。 When they are used on fluorescent paper, the written-on areas fluoresce less than the surrounding paper area when under an ultraviolet lamp。 This is especially a property of inks with a yellow tint。 Security marker pens with fluorescent ink may also be used to invisibly mark valuable household items in case of burglary。 The owner of a recovered, stolen item which has been marked in this way can be traced simply by using an ultraviolet lamp。 Items can also be marked for a variety of property marking purposes and identification。 They can also be used in readmissions such as hand stamping。 Some UV-revealed writing will be readable on a photocopy, due to the relatively strong ultraviolet component in light from the photocopier scanning head。PS。好像达芬奇密码里的馆长死之前写字用的笔也能光照显形至于配制方法。上面的材料2里面提到了aundry detergents that contain optical brighteners 好像是“含荧光增白剂的洗衣剂/去垢剂”(第7行)。可能可以吧,不过也我也没试=。=
