Generally, photoluminescence can be divided into fluorescence and phosphorescence, the delay time of the two is different. Fluorescence refers to the transition from the excited singlet state to the basic radiation transition. The fluorescence lifetime is relatively short, about the order of ps to ns...

A programmable logic controller (PLC) is a small, modular,solid-statecomputer with customized instructions for performing a particular task. PLCs, used in various industrial control systems (ICSes), have primarily replaced mechanical relays, drum sequencers and cam timers. ...
PLCs monitor the state of an input device such as signals from a light switch, and make decisions about the next state of an output device, for example switching a light on or off. PLCs are also used to transfer information from devices at factories or from offsite locations to centralize...
