A sensory system incorporated with an amplification function was developed for detection of trace-level fluoride ions. This sensory system comprises two steps, namely, amplification, and chemiluminescence. These steps were linked with chemical reactions and were induced continuously. The process from amplification to chemiluminescence was accomplished in the system by using fluoride ions. The amplification was based on a self-immolative system, which permitted the detection of emissions even at low fluoride ion concentration for system in which chemiluminescence cannot be induced in the absence of fluoride ions. An optical ratio of the chemiluminescent compound and the amplifier was calculated for achieving efficient amplification.
