Phosphor in a sentence

When the electron beam strikes the phosphor that forms the display surface it normally causes it to light up, however, if the beam energy is above a given threshold (depending on the phosphor mix) it also causes electrons to be struck out of the phosphor.

Alternatively, the LED might be paired with a remote phosphor, a preformed polycarbonate piece coated with the phosphor material.

Instead, electrons are sprayed in a wide cone across the entire front of the phosphor screen, basically making each unit act as a single light bulb. citation Each one is coated with a red, green or blue phosphor, to make up the color sub-pixels.

Prior to europium, the color-TV red phosphor was very weak, and the other phosphor colors had to be muted, to maintain color balance.

The monitor activates a phosphor on the screen during each scan if the pixel is supposed to be light, but the phosphor fades before the next scan.

Common varieties include phosphor bronze strings, which are known for their tonal warmth and brightness, 80/20 bronze, which has a bright and clear tone; and silk and steel strings, which are slightly more mellow sounding but very comfortable to play.

We also have bands of phosphor printed on the stamp for operational reasons and these are difficult to counterfeit.

The long life and low maintenance of laser phosphor projectors make them ideal for high-use settings, such as boardrooms, classrooms, houses of worship, museums, and location-based entertainment venues.

A typical low power potentiometer (see drawing) is constructed of a flat resistance element (B) of carbon composition, metal film, or conductive plastic, with a springy phosphor bronze wiper contact (C) which moves along the surface.

Conformal coating process is frequently used to address the issue of varying phosphor thickness.

Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures.

Current recommendations citation are to use the latter term. Use of the term mass spectroscopy originated in the use of phosphor screens to detect ions.

Cylinder heads fitted with cast-iron inlet valve guides, phosphor bronze exhaust valve guides, and renewable "Silchrome" steel-alloy valve seats.

Due to the simplicity of manufacturing the phosphor method is still the most popular method for making high-intensity white LEDs.

During the short period when the write takes place, the redistribution of charges in the phosphor creates an electrical current that induces voltage in any nearby conductors.

Fluorescent black light lamps use a phosphor on the inner tube surface, which emits UVA light instead of visible light.

For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor.

Gadolinium as a phosphor is also used in other imaging.

If a visible output was needed, a second tube connected in parallel with the storage tube, with a phosphor coating but without a pickup plate, was used as a display device.

In the days of CRT displays, the afterglow of the display's phosphor aided this effect.
