Sensitization in the ruby crystals activated by high concentration of ions of the titan

The authors analyzed the influence of an impurity of ions of the titan in ruby crystals introduced in the course of growth by two criteria: optical and luminescent properties. They established that in case of small concentration of ions of the titan ~ 0,003 weight % the titan contributed preservation of concentration of active ions of chrome. Introduction of high concentration of ions of the titan in ruby crystals, leads to formation of sensitized luminescence on ions of Cr3+and Ti3+.
