Commercially available silica used for TLC is considerably costly, as it is derived from non-renewable sources and also involves complex manufacturing processes. Therefore, the objective of this research was to produce fluorescent material- incorporated TLC material at a low cost for use in teaching laboratories.enManganese-doped zinc silicateRice husk ashSol-gel methodThin-layer chromatography.Article
