How do you make phosphor?
Mix two tablespoons of finely-powdered charcoal and two tablespoons of powdered cinnamon into the urine and stir.
Pour the urine/charcoal dust and cinnamon mixture into a glass retort with a glass tube leading into a second beaker filled with plain water.
Heat the retort containing the urine mixture using your torch..
Are phosphors dangerous?
The biggest immediate injury danger from a damaged lamp is from the phosphor-coated glass. If cut with fluorescent lamp glass, any phosphor that goes in the wound is likely to stop blood clotting and can interfere with curing.
Why does phosphor glow?
When a phosphor is exposed to radiation, the orbital electrons in its molecules are excited to a higher energy level; when they return to their former level they emit the energy as light of a certain color.
Are glow sticks radioactive?
In the past, the radioactive element was radium, which has a half-life of 1600 years. Today, most glowing watches use a radioactive isotope of hydrogen called tritium (which has a half-life of 12 years) or promethium, a man-made radioactive element with a half-life of around three years.
Is phosphor and phosphorus the same?
As nouns the difference between phosphor and phosphorus is that phosphor is (chemistry) any of various compounds of transition metals or of rare earths that exhibits phosphorescence while phosphorus is (chemistry) a chemical element (symbol p) with an atomic number of 15, that exists in several allotropic forms.
What is phosphor coating?
Phosphor is the luminescent material critical to many lighting applications, especially LEDs. Most white LEDs are in fact blue LEDs with a phosphor coating. Phosphor absorbs the light at the blue wavelength and reemits the photons at longer wavelengths.
What is phosphor made of?
Inorganic phosphors usually consist of a host material that could be an oxide, nitride, oxynitride, silicate, sulfide, selenide, halide or oxyhalide, doped with small amounts of activator ions like rare-earth and/or transition metal ions.
Where does phosphor come from?
Phosphor, solid material that emits light, or luminesces, when exposed to radiation such as ultraviolet light or an electron beam. Hundreds of thousands of phosphors have been synthesized, each one having its own characteristic colour of emission and period of time during which light is emitted after excitation ceases.
How do phosphors work?
Energy, in the form of light, electrons or particles, is absorbed and re-emitted at specific wavelengths. These wavelengths are dependent on the structure of the phosphor. The host crystal usually absorbs the energy and then transmits it to activator ions embedded within the crystal lattice.
Does glow in the dark last forever?
No, the glow of glow in the dark paints does not last forever. This means you cannot expect to keep the objects shining forever if you apply the paint once. … This type of paint is infused with phosphors which are energized by ultraviolet or UV light.
Can you die from glow sticks?
Dibutyl phthalate has been reported to cause anaphylaxis and even death when ingested in large quantities, but the quantities in glow sticks are pretty minimal. There is no problem if the glow stick is swallowed whole, which seems like quite a feat.
Is Phosphorus a fluorescent?
Fluorescent Light Sometimes, the phosphor coating on the inside of fluorescent lights includes phosphorus in the metallic salt lining the inside of the light bulb. These coatings produce light by having particles of radiation hit the coating from the inside of the tube, causing them to fluoresce.
