A photoconductive camera tube is a type of electron tube used in early television cameras. It works by converting light into electrical signals. When light falls on the photoconductive materials inside the tube, they change their electrical resistance, allowing the tube to capture and convert the light information into an electronic signal.

What happens when selenium is exposed to light?
Selenium is photoconductive, meaning its electrical conductivity increases when exposed to light. This property is used in applications such as photocopiers and solar cells. However, prolonged exposure to bright light can degrade selenium's performance.
What type of detector genaraly used in infrared absorption spectroscopy?
In infrared absorption spectroscopy, the most commonly used detectors are thermocouples, pyroelectric detectors, and photoconductive detectors. Thermocouples measure temperature changes due to absorbed infrared radiation, while pyroelectric detectors respond to changes in temperature by generating an electrical signal. Photoconductive detectors, often made from materials like lead sulfide or indium antimonide, change their conductivity in response to infrared light. Each type of detector has its own advantages, depending on the specific application and wavelength range.
What are the uses of polyvinylcarbazole?
Polyvinylcarbazole (PVCz) is primarily used as a photoconductive material in applications such as electrophotography and radiation detection. Its ability to form stable charge transport layers makes it valuable in organic light-emitting diodes (OLEDs) and organic photovoltaics. Additionally, PVCz is utilized in the production of polymers that require enhanced thermal and chemical stability, as well as in the formulation of coatings and adhesives.
WHAT IS A photo conductive?
I think It is a cell that absorbs light like in plants but I'm not 100%
What is seleniums chemical characteristics?
Selenium is a nonmetal with properties that vary depending on the form it takes. In its crystalline form, selenium is a semiconductor with photoconductive properties. It is also known to exhibit photovoltaic and photoresistive behavior. Additionally, selenium is unique in its ability to exist in various oxidation states (-2, +2, +4, +6).
What are photoconductive cells?
The photoconductive cell is a two terminal semiconductor device whose terminal reistance varies linearly with the intensity of incident light .
Mention the different types of photoelectric cells?
there are three types ,they are photoconductive cell ,photoemissive cell and photovoltiac cell

The process by which written or printed material is copied using static electricity is?
The process by which written or printed material is copied using static electricity is called electrostatic copying or xerography. This method involves using a photoconductive material that becomes charged when exposed to light, attracting a toner powder that is then transferred onto paper to create a copy.
