| Abstract | Praseodymium (Pr) doped SLS–ZnO glass composite material of chemical formula [(SLS)$_{0.5}$ (ZnO)$_{0.5}$ (Pr)$_{x}$] where x = 1 wt% sintered at 600, 700, 800, 900 and 1000 °C were prepared by solid state technique. The structure, morphology and luminescence properties have been characterized by X-ray diffraction (XRD), Fourier transform infrared radiation (FTIR), UV–Vis spectroscopy, photoluminescence spectroscopy (PL), field emission scanning microscopy (FESEM) and energy dispersive X-ray (EDX). The XRD, FTIR and EDX studies reveal the formation of Zn$_{2}$SiO$_{4}$ from SLS–ZnO host lattice. FESEM shown the particle size distribution would lead to a higher packing density by increasing sintering temperatures. The presence of Pr$^{3+}$ ions into Zn$_{2}$SiO$_{4}$ was confirmed by EDX analysis. The absorption peaks at 360, 444 and 616 nm originate in the UV and visible range were observed by UV–Vis spectroscopy. The PL spectrums with excitation at 444 nm exhibit two strong red emission peaks at ~613 and ~637 nm were attributed to the transition of $^{3}$P$_{o}$ → $^{3}$H$_{6}$ and $^{3}$P$_{o}$ → $^{3}$F$_{2}$. It is found that Pr$^{3+}$ ions substituted into the host lattice could improve to the luminescence properties with increasing sintering temperatures. These results indicate that Pr doped SLS–ZnO exhibits great potential red phosphors in WLEDs application. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
