What Is Fluorescence? – Find Out What It Is and What It Has To Do With Making Glow Sticks Light Up
If you’ve ever used glow sticks, you have used fluorescence! Those toys that kids love to use on Halloween, make illuminated jewelry, and decorate their parties with are all the rage. But just what is fluorescence?
Fluorescence is the release of energy by an element or ingredient that has taken up light or other electromagnetic radiation. You probably have fluorescent lighting in your home or your office. There is a mercury vapor in the bulb. This lights up the bulb when ultraviolet light passes through it via an electrical current, causing the bulb to light up. It’s a much more efficient way of lighting a room than incandescent lighting, which can be hot and be more expensive to burn.
If you have a real diamond ring, you have fluorescence! Yes, there is fluorescence in diamonds. The reaction between the minerals in diamonds makes it glow brightly, especially when exposed to ultraviolet light, like the sun. If you go shopping for a diamond ring, chances are that the lighting in the shop will be fluorescent lighting for that diamond to shine as brightly as it can.
LED fluorescence microscopy is a source of illumination that gives excellent image quality and can last a long time. Used in laboratories, this type of microscopic inspection is used for the diagnosis of tuberculosis, especially in developing countries with this disease as an issue. The fluorescence is a great improvement over conventional light microscopy, detecting 10% more TB cases then the conventional did. The light emitted is a big advantage, plus the life span of this microscope is much longer than a conventional one.
In order to detect the structure of tiny molecules, laser induced fluorescence can be effectively used. The animal or object being studied is excited with a laser. This will allow a light to be emitted at a long enough fluorescent wavelength and then is recorded with a specialized type of phototube. Since fluorescence can be seen in all directions (remember that diamond ring shining?), that signal is very easy to detect. Laser induced fluorescence is used to study molecules, such as fluorescent dyes, and their interactions.
To discover more about this subject, you can read about it in the Journal of Fluorescence where studies using this spectroscopic technique are written up and peer-reviewed by scientists.
It is the fluorescent dyes contained in the tubes of glow sticks that release the light when the chemicals are combined once the stick is bent. A chemiluminescent reaction occurs and the energy is released in the form of glowing, usually multi-colored lights.
