    摘要： A method for recording and reproducing an X-ray image is provided which method comprises the steps of :

    (1) causing a photostimulable phosphor to absorb image-wise or pattern-wise modulated X-rays,
    (2) photostimulating said phosphor with stimulating electromagnetic radiation selected from visible light and infrared light to release from the phosphor in accordance with the absorbed X-rays electromagnetic radiation different in wavelength characteristic from the radiation used in the photo-stimulation, and
    (3) detecting said light emitted by photostimulation,

    wherein said phosphor is an oxyorthosilicate corresponding to the following empirical formula (I) :



            Y₂SiO₅:Ce³⁺, Sm³⁺   (I)



    wherein :
    Ce³⁺ is present in an atomic percentage in the range from 0.01 to 5 with respect to the yttrium concentration taken as 100 atom %,
    Sm³⁺ is present in an atomic percentage in the range from 0 to 5 with respect to the yttrium concentration taken as 100 atom %.

    摘要： Method for the preparation of a phosphor by firing a mixture of the raw materials of the phosphor, wherein prior to firing said mixture the following steps are carried out :

    (I) mixing the raw materials of the phosphor in an aqueous medium in finely divided state while at least one of said materials is present as a sol,
    (II) transforming the sol into a gel while it is intimately mixed with the other finely divided raw materials, and
    (III) drying the gel to form a xerogel.
