Disclosed is a preparation method of a radiation image conversion panel by a vapor deposition method, in which a support member is supported and rotated and the stimulable phosphor evaporated from the evaporation source is deposited onto the support member to form a stimulable phosphor layer. The radiation image conversion panel manufactured by the method is also disclosed.

Radiation image conversion panel and preparation method thereof

A lithium ion capacitor includes a positive electrode made of a material capable of reversibly doping and dedoping lithium ions and/or anions; a negative electrode made of a material capable of reversibly doping and dedoping lithium ions; and an electrolytic solution made of an aprotonic organic solvent electrolyte solution of a lithium salt. When the negative electrode and/or positive electrode and a lithium ion supply source are electrochemically brought into contact, lithium ions are doped in a negative electrode and/or positive electrode. A positive electrode potential after the positive electrode and negative electrode are short-circuited is 2.0 V (vs. Li/Li) or less. The positive electrode and/or negative electrode has a current collector made of a metal foil that has many holes that penetrate through both sides and have an average diameter of inscribed circles of the through-holes of 100 &#x3bc;m or less.

Lithium ion capacitor

A radiographic image conversion panel containing a substrate having thereon a phosphor layer formed by a vapor-accumulating method, wherein the phosphor layer has a thickness distribution of not more than &#xb1;20%, the thickness distribution being defined by the formula: ((D&#x2212;D)/(D+D))&#xd7;100, provided that Dis a maximum thickness of the phosphor layer; and Dis a minimum thickness of the phosphor layer.

Radiographic image conversion panel and production method thereof

A radiation image conversion panel is disclosed, comprising a support having thereon a stimulable phosphor layer formed by vapor deposition of a stimulable phosphor, wherein the stimulable phosphor layer meets the following requirement:wherein A is a thickness (&#x3bc;m) of the stimulable phosphor layer and B is a transmittance (%) of a stimulating light or a stimulated emission.
