In real live plasmas give off some odor. The closest to a reference I find is this. But one can easily check for himself. It's mostly ozone what one smells (smell of thunderstorms).

So I was wondering as lightsabers are kind of plasma and we sometimes see even flashes between blades - do lightsabers have a peculiar odor?

I would especially be interested if there was anything mentioned in books - like one could smell there was recently a fight in a room.

    Are you especially interested in the EU novels? There are literally dozens of references to lightsabers having a "tang" and "smell" of ozone. – Valorum Jun 17 '17 at 9:45

    I didn't realise there are. But as you ask - is there any instance where this was used on it's own? say to track someone, or as in the question as evidence there was a battle (which otherwise wouldn't be apparent). – bdecaf Jun 17 '17 at 10:13

    No, they don't smell. They've got no nose. – Nicholas Shanks Jun 17 '17 at 13:19

    Seems like they must smell the same as the beam of a super-hot laser (ozone). Of course there could be less smell because a light saber inexplicably has properties and limitations that are different from a laser. – Mark Rogers Jun 17 '17 at 15:52

    @MarkRogers or real live plasma. though I was not sure chemistry in a galaxy-far-away would work the same. Now I wonder whether Vaders asthma was induced by inhaling all this ozone... – bdecaf Jun 17 '17 at 16:00

There seems to be a particular smell associated with lightsabers; Ozone.

A burning blade of green slanted across the sergeants face so close he could smell the ozone, and the hunchback wasn’t a hunchback anymore: he now held a lightsaber the color of a summmer sky, and he said in a clipped, educated Coruscanti accent, “Please don’t try to resist. No one has to get hurt.”

It's more pronounced when the saber comes into contact with electricity

*He was lost in his own thoughts when Qui-Gon swung about with such swiftness it caught the boy completely by surprise. Down swept the Jedi’s lightsaber in a brilliant arc, cutting through the shadows between two buildings, clashing momentarily with something made of metal that shattered in the wake of the weapon’s passing. * Qui-Gon clicked off the lightsaber and knelt to inspect a cluster of metal parts still sparking and fizzing in the sand. The acrid smell of ozone and burning insulation hung in the dry air.

and

“Help me! I can’t hold on any longer!” The yellow glare from Palpatine’s eyes spread outward through his flesh. His skin flowed like oil, as though the muscle beneath was burning away, as though even the bones of his skull were softening, were bending and bulging, deforming from the heat and pressure of his electric hatred. “He is killing me, Anakin-! Please, Anaaahhh-“

Mace’s blade bent so close to his face that he was choking on ozone. “Anakin, he’s too strong for me-“

    I'm convinced that Valorum is some kind of robot at this point. – Recelica Jun 17 '17 at 10:14

    @bdecaf - I think the implication is that you get more ozone, the more the blade is interacting with the air. Merely waving it around generates a little ozone. Cutting something with it generates a lot. – Valorum Jun 17 '17 at 12:06
