Abstract
The fabrication of nanocomposite photonic materials suggests their use in a wide variety of applications. An essential requirement for such materials is their photostability and high photobleaching resistance. Both lanthanides and quantum dots are good candidates for embedding in the polymer matrix to obtain highly luminescent nanocomposites. This paper presents the concept for the ratiometric optical pulsed laser power sensor based on terbium and red-emitting semiconductor quantum dots co-doped polymer luminescent nanocomposite for application in inexpensive laser monitoring systems.
