According to my research, "Disruptor" describes the effects of the weapon, not the energy form it uses. Mainly, it disrupts the atomic structure of the matter it impacts.
In several episodes of TNG, they would refer to a klingon disruptor as a phaser. My understanding is that a proper "disruptor" weapon simply has no stun setting. Apparently, the KDF weapons are just phasers that operate on a different frequency and a higher, less controlled, power level.
So, according to treknology, there is no "disruptor" energy type. There is Nadeon (Starfleet Phasers, KDF Disruptors), Plasma, Tetryon, Polaron, etc.
