Abstract
Zn3V2O8 (or ZVO) nanophosphor was prepared using a simple solution-combustion technique and sintered at 700–800°C for 5 h. The effects of additive and sintering temperatures on structural, morphological and optical properties have been investigated. The structural studies revealed an orthorhombic phase structure. The d-spacing and lattice constants also increased with the sintering temperature. The microplate-shaped morphology of ZVO sintered at 750°C is confirmed by SEM and TEM pictures, with an average grain size of roughly 3–5 μm. The optical energy gap of the direct transition is also estimated, and it decreases from 3.4 to 3.1 eV with the increase in sintering temperature. The ZVO also demonstrated a broad photoluminescence (PL) emission range between 450 and 600 nm, with a peak at 534 nm, indicating green luminescent emission. Large grains with microplate shapes emit the highest PL intensity in ZVO phosphor at 750°C.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
