SENSOR ÓPTICO MULTIFUNCIONAL PARA DETECÇÃO DE O2 E OXIGÊNIO DISSOLVIDO
Abstract
Oxygen (O2) and dissolved oxygen (OD) sensors are of great importance to monitor the quality of water in rivers and in the environment. Conventionally sensors applied for this purpose are based on photoluminescent emission of dying molecules which require photoluminescent equipment. In this context, the present work reports the fabrication and response analysis of sensors based on photoluminescent emission of platinum octaethylporphyrin (PtOEP) molecules that were directly deposited on the active region of an optoelectronic detector. The sensors fabricated in this way showed excellent response to O2 and DO allowing great possibilities of application for in situ monitoring systems.
