A method of producing a double-doped scintillation crystal is provided. Czochralski method is used to grow a double-doped single crystal boule. The double-doped single crystal boule is a single crystal boule of rare-earth silicate double-doped with cerium (Ce) and calcium (Ca) or magnesium (Mg). The double-doped single crystal boule is subjected to a thermal annealing process in a furnace. A yield of pixel samples of the double-doped scintillation crystal is improved after a processing process, and the present invention achieves low producing cost, high yield, less crystal fragmentations, high luminescence intensity and short decaying time.
