Photoluminescence, thermoluminescence and Raman studies of CdS nanocrystalline phosphor

Nanohybrid MoS2-PANI-CdS photocatalyst for hydrogen evolution from water

“…2B shows a selected region of Raman spectra of the composites along with MoS 2 , PANI and CdS. Raman spectrum of CdS shows two main bands around 301 and 602 cm −1 , which can be assigned to 1 LO (longitudinal optical) and 2 LO phonon modes of CdS, respectively [17]. Raman spectrum of MoS 2 is characterized by two main intense bands at 383 and 407 cm −1 .…”

Synthesis and luminescence studies of CdSrS nanostructures

“…Method-2: The starting materials, CdS [21], SrS [23], Bi(NO 3 ) 3 ·5H 2 O and S (A.R. grade), were weighed and mixed to obtain the prescribed composition.…”

“…More recently, we have reported the luminescence of undoped and Bi doped CdS [21] and SrS:Bi [22,23] nanostructures. The SrS compounds crystallize only in the rock salt structure which is incompatible with the zincblende or wurtzite structure in which II B -VI B compounds crystallize [24].…”

Thermoluminescence and kinetic analysis of Gamma irradiated Bi doped SrS nanocrystalline phosphors

“…Marwaha et al [8,9] and Sweet and Rennie [10] have explored the potential of these materials as efficient X-ray, UV and gamma dosimeters. Currently, nanotechnology and nanomaterials have attracted several researchers from different fields, especially from the field of luminescence; as they exhibit enhanced optical, electronic, and structural properties [11][12][13][14]. TLD materials, having nanostructure forms, have also been prepared and their TL responses to ionizing radiations were studied [15,16].…”

“…Though CaS in microcrystalline form dominates all sulfides in respect of their use in TL dosimetry, it is also worth reporting the TL properties and trapping parameters of other sulfide nanophosphors. Recently, we have reported the thermoluminescence of undoped and Bi doped CdS (group II B -VI B ) nanostructures exposed to ␥-radiations [12]. It is known that host-dopant combination plays a significant role in controlling the PL and TL properties of the luminescent materials [22].…”
