Pure and manganese-doped ZnO thin films are synthesized by sol-gel dip coating to characterize how manganese doping affects their structure and properties.

Manganese doping shrinks ZnO crystallite size from 28 to 7 nm while keeping films selective to ammonia, with the best-performing film giving roughly 5x the undoped response and 60-day stability.
