Abstract
The present invention aims to provide a photostimulable phosphor for obtaining a two-dimensional or three-dimensional dosimeter, the photostimulable phosphor exerting superior handleability, exhibiting superior biological equivalence, and having superior precision. The present invention also aims to provide a laminate using the photostimulable phosphor. The aforementioned objects are achieved by means of a method for producing a photostimulable phosphor, the method comprising a step A for mixing lithium tetraborate, boron oxide and silver oxide and a step B for obtaining the photostimulable phosphor comprising lithium heptaborate as a base material and silver as a luminescent center present in the base material by firing the aforementioned mixture at 820 to 860° C., wherein the molar ratio between the lithium tetraborate and the boron oxide in the step A is X:1 (X>1), and the amount of the silver oxide is 0.06 to 1.0 mass % relative to the total mass of the lithium tetraborate and the boron oxide.
