With the unique structural features the metal borates are widely used in the aspects of catalysts, molecular sieves, magnetism and op-tics. The metal borates commonly includes rare earth metal borates, alkaline earth metal borates, rare earth and alkaline earth metal complex borates,binary metal rare earth borates and poly-borates. The activated ions are mainly rare earth ions and transition metal ions, including rare earth ion sin-gle doping, transition metal ion single doping, rare earth ion double doping, rare earth ions and transition metal ions double doping. The optical prop-erties and luminous mechanism of rare earth metal borates are summarized, and the synthesis methods and applications for different kinds of rare earth metal borates are briefly introduced.
