Porous silicon microcavities with embedded conjugated polymers for explosives detection

It is known that development of optical sensors for explosives detection is currently of great interest. Among others sensors based on the luminescence quenching of conjugated polymers caused by photoinduced electron transfer have attracted considerable attention. Embedding such polymers into porous silicon (pSi) microcavity (MC) allows modify its luminescence spectrum and increase specific surface area and sensitivity of sensor. At the same...
