Application number: 200810167894.8 Application date: 2008-10-16
Abstract: A kind of bromide The preparation method of lanthanum cerium scintillation crystal is characterized by: when configuring the lanthanum cerium bromide crystal growth raw material, other ions (reinforcement agents) are mixed to increase the crack resistance strength of the crystal. This reinforcement ion can be a trivalent ion. , can also be divalent or tetravalent ions; the crystal is grown using a special hanging quartz crucible descent method. Due to the dislocation pinning effect of the reinforcing agent ions, the present invention prevents dislocation diffusion and crystal plane slip, effectively prevents crystal cracking during growth and processing, and greatly improves the strength of the prepared lanthanum cerium bromide single crystal. Strength, improves crystal quality.
