Description
Europium trihydroxide is a chemical compound with the formula Eu(OH)3, which is derived from the rare earth element europium. It is known for its unique properties and applications in various industries due to its ability to absorb and emit light, making it a valuable material in the field of optics and electronics.Uses
Used in Display Technology:Europium trihydroxide is used as a phosphor activator for color cathode-ray tubes (CRTs) and liquid-crystal displays (LCDs) used in computer monitors and televisions. The application reason is its ability to enhance the color quality and brightness of these displays.
Used in Energy Efficient Fluorescent Lighting:
In energy-efficient fluorescent lighting, europium trihydroxide is used to provide not only the necessary red but also the blue component of the light spectrum. This application is due to its ability to absorb and emit light in the visible range, contributing to the overall color balance and energy efficiency of the lighting system.
Used in Commercial Blue Phosphors:
Europium trihydroxide is also used in the production of several commercial blue phosphors for color television, computer screens, and fluorescent lamps. The application reason is its unique optical properties, which make it an ideal candidate for creating high-quality and energy-efficient light sources.
Check Digit Verification of cas no
The CAS Registry Mumber 16469-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,6 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.Calculate Digit Verification of CAS Registry Number 16469-19:
(7*1)+(6*6)+(5*4)+(4*6)+(3*9)+(2*1)+(1*9)=125
125 % 10 = 5
So 16469-19-5 is a valid CAS Registry Number.
