    • In a method of consecutively manufacturing a set of at least 5 storage phosphor plates by a vapor deposition process in one and the same vapor deposition apparatus, in said apparatus, before starting each vaporization, refractory material surfaces are brought into contact, in a crucible unit thereof, with liquefied raw materials of a matrix component and an activator component, a phosphor precursor component or a combination thereof, wherein deviations in speed from one plate to another within said set of storage phosphor plates are less than 15%, said deviations being expressed as a variation coefficient defined by following formula (SAL % dev/SAL % av)×100, provided that SAL % av stands for an averaged speed within average speeds over each of said storage phosphor plate surfaces within said set and that SAL % dev stands for a standard deviation of averaged speeds obtained from each phosphor plate within said set, wherein a step of increasing said refractory material surfaces is included by adding to said crucible unit, before starting vaporization in the manufacturing of each of said plates in said set, refractory particles selected from the group consisting of a powder, crystalline particles, amorphous particles, spheres, bars, sticks, ingots and curls or a combination thereof.
    • 在一种相同的气相沉积设备中通过气相沉积工艺连续地制造一组至少5个储存磷光体板的方法中,在所述装置中,在开始每次蒸发之前,耐火材料表面在坩埚单元中接触 其中具有基质成分和活化剂成分的液化原料,荧光体前体成分或其组合,其中在所述一组存储磷光体板内从一个板到另一个板的速度偏差小于15%,所述偏差表示为 作为由以下公式(SAL%dev / SAL%av)×100定义的变化系数,只要SAL%av表示在所述组内的每个所述存储磷光体板表面上的平均速度内的平均速度,并且SAL%dev代表 从所述组中的每个荧光板获得的平均速度的标准偏差,其中增加所述耐火材料表面的步骤是包括的 通过在所述组中的每个所述板的制造中开始蒸发之前,通过添加到所述坩埚单元,从由粉末,结晶颗粒,无定形颗粒,球体,棒,棒,锭和卷曲组成的组中选择的耐火材料颗粒,或 其组合。
