Synthesis and characterization of strongly fluorescent europium-doped calcium sulfide nanoparticles

Thermoluminescence characteristics of gamma irradiated CaS:Ce nanophosphors

“…Being a wide bandgap (4.43 eV) [7] semiconductor, it is investigated with wide range of dopants such as Sm 3+ , Ce 3+ , Eu 2+ , Bi 3+ , etc. [11][12][13][14]. These days nanotechnology has stimulated interest in the properties of nano form of the matter.…”

Burstein Moss effect in nanocrystalline CaS : Ce

“…In the present study we have prepared CaS : Ce nanophosphors using wet chemical co-precipitation method (Sun et al 2002) and studied their optical absorption characteristics with varying cerium concentrations.…”

“…Sun et al (2002) prepared CaS : Eu nanoparticles through wet chemical co-precipitation method and obtained monodispersed particles with narrow size distribution. Sun et al (2002) and Kumar et al (2006) prepared CaS : Bi nanoparticles with the same method. Sawanda et al (2006) prepared CaS : Eu nanoparticles using alkoxide method.…”

Studies on luminescence properties and energy transfer in Ce/Dy co-doped CaS nano-phosphors

“…CaS is a wide band gap semiconductor hence can accommodate a variety of dopants [16][17][18][19]. Its emission color can be tuned over a large part of the visible spectrum, by changing the dopants.…”
