什么化学物质在紫外光照射下会发荧光?

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）

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=.=
