Novel SnO₂ based optical sensor for detectin of low ammonia concentration in water at room temperatures

Novel SnO₂ based optical sensor for detectin of low ammonia concentration in water at room temperatures

In the work, presented are preliminary experimental results on the capability of a metal oxide (MO) based optical sensor to perform ammonia detection in water environment at room temperature. The electro-spray pyrolysis technique was used to deposit SnO₂ films on the distant end of standard silica o...
