Tm+3decay in chromium-thulium-holmium-doped yttrium aluminum garnet at liquid helium temperatures Academic Article uri icon

abstract

  • The standard expression for the excited‐state acceptor concentration in codoped solid‐state materials is modified to include the possibility of nonradiative acceptor deexcitation. The chromium and thulium time‐dependent emission in yttrium aluminum garnet (YAG) is then studied; evidence is given for the identification of the tendency for localized correlated chromium‐thulium pairs in the crystalline material.
