What is used in television tubes to produce the color red?
Europium
2 types of phosphor dot?
P22 phosphor dot: Used in color CRT displays, it emits red, green, and blue colors when excited by electrons. P31 phosphor dot: Generates brighter and more saturated colors compared to P22 dots, and is often used in higher-end CRT monitors for improved image quality.
Is a phosphor a cehmical?
Yes, a phosphor is a chemical compound or substance that exhibits phosphorescence, the ability to emit light after being exposed to a source of energy such as light or electricity. These materials are commonly used in fluorescent lights, cathode ray tubes, and other devices to produce visible light.
What is a phosphor activator?
A phosphor activator is a chemical substance added to a phosphor material to enhance its luminescent properties. It works by promoting the efficiency of the energy transfer process within the phosphor material, leading to brighter and more long-lasting light emission.
Function of the phosphor in fluorescent?
The phosphor in a fluorescent light bulb converts ultraviolet light emitted by the mercury vapor into visible light. This process creates the bright, white light that we see when a fluorescent bulb is turned on.

What is phosphorus in German?
Phosphor.
What is the Kannada word for 'phosphor'?

What is a phosphor blend?
A mixture of two or more different phosphor chemicals to produce a selected perceived color or color temperature, that cannot be produced by a single phosphor chemical. Such blends may be used on the face of CRTs, in fluorescent lamps, in special LEDs, etc.
When was Phosphor - album - created?
Phosphor - album - was created in 2000.

The material used for construction of the baulk ring?
copper based alloy, Phosphor bronze ;)
How well does phosphor bronze conduct electricity?
Phosphor bronze is a good conductor of electricity, although not as efficient as pure copper. Its conductivity is influenced by the alloy composition and can vary. Overall, phosphor bronze is commonly used in electrical components and connections due to its good conductivity and corrosion resistance.
Is a phosphor a cehmical?
Yes, a phosphor is a chemical compound or substance that exhibits phosphorescence, the ability to emit light after being exposed to a source of energy such as light or electricity. These materials are commonly used in fluorescent lights, cathode ray tubes, and other devices to produce visible light.
Why is phosphor- bronze wire used in moving coil galvanometer?
restoring torque is k theta the value of k depends upon the nature of the material used for suspension strip value of k is very small for quartz or phosphor bronze so in galvanometer phosphor bronze wire is used.
Why worm gear is made up of phosphor bronze?
The phosphor bronze is resilient and have a low coefficient of friction.
Why phosphorous used in CRT?
CRT televisions consist of a controlled flow of electrons hitting precisely at phosphor dots of colours red, green and blue, arranged behind the glass screen of the television set. When an electron hits one of these phosphor dots, the respective colour of the phosphor dot shines for a very short duration. This is the basic principle of the working of the CRT. Thus, phosphor plays a very important role in the generation of colour pictures in the CRT
