Slander is spoken / libel is in print - written or published defamatory statement, and both are components of defamation suits. This is an area of law that provides a civil remedy when someone's words end up causing harm to your reputation or livelihood. Defamation varies from state to state, but generally to prove it you will have to show there's been a statement that is all of the following: published / false / injurious / unprivileged. Truth is a defense. Because of Free Speech and 1st Amendment issues the pursuits of these claims/cases are costly and protracted.

What you describe is a case in defamation. Under Nevada law, there really are two types of such actions....
First is defamation per quod, in which you shall have to show some economic damage to have an actionable claim. In other words, unless this person's lies about you (truth is the absolute defense) ended up costing you a job, some customer business, a sale or some other direct, financial injury, a suit would be completely hollow and meaningless.
The second type is defamation per se. This is when the slander or libel falls into a few specific categories of lies told (or written) about another person. In this case, you do not have to prove you lost money, just that the defamation took place.
Generally speaking, victims of defamation are only entitled to recover non-economic damages if they also suffered economic damages or if the defamatory speech:
* claimed the victim committed a crime;
* accused the victim of suffering from a communicable or loathsome disease; or
* prejudiced the victim in his/her profession or business.
It sounds from your brief inquiry that you were accused of a crime and you deny it. That clearly is one of the above categories eligible for non-economic damage claims.
You should also know that Nevada law specifically provides for a civil action in a case where a person files a false criminal complaint. If that occurred, you might look to Nevada Revised Statute 41.508 to see the criminal penalties and certain rights you may have as a victim of such misconduct.
You really need to have a competent Nevada lawyer review the facts of your matter to see if you have a meritorious claim to make.
