Chemiluminescence Lab Report

Procedure: In this experiment, various chemicals were mixed together, to determine a reaction. Using two drops from chemical 1 and two drops of chemical two, unless otherwise stated, then recording the type of physical reaction or color changes that occurred.

The experiment can also be done to compare the burn rate of different colored candles.

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.

In this science experiment there will be a reaction. The reaction between the peroxide and yeast. The yeast is the last thing you add because when you add it the yeast acts as a catalyst to release the oxygen molecules from the peroxide. The foam is oxygen filled bubbles. At the end

What essentially happens in these reactions is that first, light breaks the bond between two bromine atoms, from a

In this experiment, luminol was synthesized in the lab and used to demonstrate the result of the chemiluminescence reaction.

A glow stick consists of a glass vial housed inside a larger plastic vial. When you bend the stick, the glass vial breaks. This allows the two solutions to flow together and mix. The resulting chemical reaction causes a fluorescent dye to emit light according to the reaction shown on the right. The type of fluorescent dye determines the color of the glow stick.

Most of us have memories of glow sticks. I have a warm memory of glow sticks. I would stand on the back porch with my family shaking the glow sticks back and forth on special holidays like birthdays, Halloween, Independence Day, and Christmas. The problem was that the sticks rarely lasted long enough for you to get in the holiday spirit. Of course, that required you to use several more sticks that also did not last very long. However, manufacturers have developed long lasting glow sticks that last for several hours. It is easy to wear the glow sticks during Halloween, while trick or treating and much more.

Light is the product of a natural process, where electrons reach an excited state and then

The firefly also known as, photinus pyralis, is a distinctive and unique specie as it makes itself glow, mainly to attract a mate. Bioluminescence is a fascinating process by which organisms convert chemical energy to cold light. Inside the firefly’s lantern are the chemicals – luciferin and luciferase. When luciferin and luciferase are mixed together in the presence of oxygen and ATP, the fuel for the cell, the chemical reaction gives off energy in the form of light. Bioluminescence chemical reactions use natural resources that are easily replenished and are renewable – so it doesn’t ware off or lose its glow.

It makes its tail glow using bioluminescence which is a chemical reaction between a chemical the glow worm makes called luciferin mixes with air. That chemical reaction gives off light.

Lasers work by using a process called stimulated emission which allows an incoming photon (of a precise level) to interact with an excited atomic electron. Stimulated emission allows three things to occur. The first is the light from a laser being monochromatic. This means that the light is of only of one specific wavelength of colour. The wavelength of light is decided by the amount of energy released when the electron drops into a lower orbit. Light can only be released when an atom has become excited and gives off an electric discharge which causes the electrons to drop form a high energy orbit into a lower energy orbit. The second is coherency; this is the organization of the light. Every photon moves in a specific time to match the others. Therefore each photon has wave fronts that take-off in unison. The third is the direction of the light. The light has a very concentrated beam and is very strong. Ordinary light do not have these properties. The light of a flashlight is very spread out and disorganized unlike the light of a laser.

The PSU researchers first noticed the power of the six-inch light sticks in spring of 2015 when a group of investigators placed dozens of the glow sticks in funnel traps on game lands

They are already packaged in a way to emit focused light. This is a useful characteristic to feature illumination like in jewelry shop. And, being a solid-state device they are difficult to damage with shock.

After that, blue and white diodes were made. The blue diodes helped with the creation of the white diodes. Researchers decided to coat the blue LEDs with phosphor (a fluorescent fluid) to make the blue LEDs look white. All of this allowed LEDs to be used in traffic lights, flashlights, and TVs.
