Abstract
We have recently measured two photon excited emission spectra of $K_{2}PtCl_{6}$ as a single crystal at 77 and $2^\circ K$. Luminescence near 560 nm was monitored and distinct excitation features were found at 700 and 940 nm. These correspond to two-photon transitions of 28,500 and $21,300 cm^{-1}$ respectively. This data suggests an alternate assignment of the $PtCl_{6}^{-2}$ one photon spectrum which will be discussed.
