It is more correct to talk about "APS-C" anf "FF" or "full frame". DX is Nikon speak for designed for APS-C image circle.
DSLR lenses from Nikon that are designed for the smaller APS-C image circle have "DX" in their name. The lenses designed for the bigger FF image circle have no "DX" in the name.
For Tamron: APS-C: Di II. FF: Di.
For Sigma: APS-C: DC. FF: DG.
For Tokina: APS-C: DX. FF: no DX in the name.
Not for Nikon, but just to make the list complete:
Sony: APS-C: DT. FF: no DT in the name.
Canon: APS-C: EF-S. FF: EF.
Since the Tamron has Di in its name, it will work well on both APS-C and FF cameras.
