Abstract
The article presents a nanocrystalline semiconductor material - porous silicon - and its application possibilities. We would like to offer a popular insight into principles of visible photoluminescence of porous silicon and ways leading to the construction of chemical sensors for gas phase (electronic noses).
This paper aims at broadening of horizons in the interdisciplinary fields of physics - chemistry - nanomaterials and the subsequent use in physics and chemistry high school lessons. This subject can also be a supplement of a set of interesting and simple experiments dealing with the luminescence phenomenon [1].
