Influence of Pr,Sm,Dy on the Emission Spectra of YAG∶Nd |

| Abstract: | A series of YAG∶Nd,Re(Re=Pr,Sm,Dy) were synthesized by using the sol-gel method, and their spectral properties were studied. It proves that Pr 3+ , Sm 3+ and Dy 3+ have a quench influence on the emission spectra of YAG∶Nd. The Pr 3+ ,Sm 3+ and Dy 3+ must be removed in laser materials because they are harmful impurities. |
