A new instrument for X-ray luminescence spectrum was established in order to study properties of X-ray luminescence materials

which consists of X-ray generator

optical fiber and fluorescence spectrophotometer and can determine spectral distribution graph

time-change graph

afterglow decay curve. The results showed that both of stability and precision are fine and relative standard deviation(RSD)is less more than 2%. The instrument simplifies the process for determining X-ray luminescence materials.
