1315-07-7 Usage
Description
Strontium selenide (SrSe) is a white cubic crystal with the molecular formula SrSe and a molecular weight of 166.5852 g/mol. It has a CAS number of 1315-07-7, a melting point of 1605°C, and a density of 4.54 g/cm3. Strontium selenide is sensitive to water, which prevents its preparation through aqueous precipitation methods. It can be synthesized by reacting the oxide with selenium (Se) metal or by reducing the selenate with hydrogen gas. Both strontium selenide and barium selenide exhibit a simple cubic structure, with cube edges measuring 3.117 ? and 3.308 ?, respectively.
Uses
Used in Infrared Detection Applications:
Strontium selenide is utilized as an infrared stimulable phosphor, which is essential for the detection of infrared light. Photoluminescent materials are prepared using a base material like SrSe, and up to three dopants, such as Sm3?, Ce3?, and Eu2? compounds, are used to provide electron traps. The base material can be a combination of alkaline earth metal selenides, including strontium selenide, calcium selenide, or a mixture of these.
In this context, a "stimulable" phosphor refers to a material that stores energy absorbed upon exposure to excitation by electromagnetic radiation and releases the predominant portion of the stored energy upon exposure to stimulating electromagnetic radiation at room temperature (about 20°C). This property makes strontium selenide a valuable component in the development of advanced infrared detection systems.
Check Digit Verification of cas no
The CAS Registry Mumber 1315-07-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1315-07:
(6*1)+(5*3)+(4*1)+(3*5)+(2*0)+(1*7)=47
47 % 10 = 7
So 1315-07-7 is a valid CAS Registry Number.
