We study irreducible spherical unitary representations of the Drinfeld double of the q-deformation of a connected simply connected compact Lie group, which can be considered as a quantum analogue of the complexification of the Lie group. In the case of SU q (3) \mathrm{SU}_{q}(3) , we give a complete classification of such representations. As an application, we show the Drinfeld double of the quantum group SU q (2 n + 1) \mathrm{SU}_{q}(2n+1) has property (T), which also implies central property (T) of the dual of SU q (2 n + 1) \mathrm{SU}_{q}(2n+1).
