If I were writing out chords, I would just call them "diminished," but I believe it is musically correct to call them "fully diminished 7th" or just "diminished 7th" chords, and I believe this is a common way to abbreviate that.

The 7th interval in a "half-diminished" chord, after all, is minor, not diminished.
