Abstract: A standard light source utilizing spontaneous radiation made by mixing a fluorescent substance LnVO4:X (wherein Ln is Y or Gd, and X is Dy or Eu) with a radioactive substance containing a radioactive isotope which is less in the degree of temperature variation of the intensity of emitted light and excellent in stability. Particularly when used in a light-receiving device having photomultiplier tubes, the said light source emits light quite similar to that of a thermoluminescent substance such as CaSO4:X (wherein X is Im, Dy, Sm or Mn), LiF or Mg2SiO4:Tb, and is excellent as a calibration high-stability standard light source for use in the above-mentioned light-receiving device.
Abstract translation: 使用通过将荧光物质LnVO4:X(其中Ln是Y或Gd,X是Dy或Eu)与放射性物质混合的标准光源与放射性物质混合,所述放射性物质的温度变化程度较小 发光强度高,稳定性好。 特别是当用于具有光电倍增管的光接收装置中时,所述光源发射与CaSO 4:X(其中X为Im,Dy,Sm或Mn),LiF或Mg 2 SiO 4:Tb等热致发光物质相似的光 并且作为用于上述光接收装置的校准高稳定性标准光源是优异的。
