In this paper, NaCl: Cu circular dose tablets with a size of 5x1.8mm are prepared by sintering pure NaCl and CuCl powder as raw materials. They are placed in a four-element shell and sealed with plastic film to overcome the moisture absorption of the material. Their photoluminescence characteristics are studied by using an Inlight 200 automatic photoluminescence measurement system. The results show that the X-ray characteristic peaks of NaCl: Cu sintered at 650 degrees C and 400 degrees C appear at 27 degrees, 32 degrees, 45 degrees, 56 degrees, 66 degrees, 75 degrees and 84 degrees respective...
