Development of alkaline earth sulphide based nanophosphors embedded in PDMS polymer matrix for UV sensor applications
Properties of CaS:Ce were studied for its application in UV sensor. Luminescent CaS:Ce nanobelts were synthesized via solid state diffusion method. These nanobelts were embedded in PDMS (Polydimethylsiloxane) in order to increase chemical stability against moisture in the ambient surrounding. The XRD pattern of CaS:Ce and luminescent-PDMS was found to be in agreement with standard data. Particle size calculated using Debye Scherrer formula was found to be ∼50 nm. A slight variation in particle size and lattice parameter was observed after embedding in PDMS. Morphology of as prepared samples was analysed using SEM and nanobelts like structure was observed. This luminescent-PDMS films showed similar PL characteristics (excitation and emission) as that of CaS:Ce indicating that PDMS does not interact with CaS:Ce. The design for UV sensor using CaS:Ce in 200nm–400nm is proposed.
