A radiation image storage panel comprises at least a substrate and a phosphor layer overlaid upon the substrate. The phosphor layer contains a binder, a phosphor, and at least one kind of organic phosphorus compound represented by Formula (1):
(R)
n
PO (OM)
3−n
(1)
in which R represents an alkyl group, an aryl group, or a heterocyclic group, which may be optionally substituted by a substituent;
M represents a hydrogen atom, an alkali metal, or −N
+(R
1
)
4
, where R
1
represents an alkyl group having at most two carbon atoms; and
n represents an integral number of 1 or 2. The radiation image storage panel exhibits enhanced dispersibility of phosphor particles and a high sensitivity and yields little noise.
辐射图像存储板至少包括一块基板和覆盖在基板上的荧光粉层。荧光粉层包含粘合剂、荧光粉和至少一种由式(1)表示的有机
磷化合物:
(R)

PO (OM)
3-n

其中,R 代表烷基、芳基或杂环基,可任选被取代基取代;
M 代表氢原子、碱
金属或 -N

其中 R
1
代表最多有两个碳原子的烷基;以及
n 代表 1 或 2 的整数。辐射图像存储板具有更高的荧光粉颗粒分散性和高灵敏度,产生的噪音很小。
