Description

This book is aimed at providing a sound introduction to the halophosphate phosphor to undergraduate, post graduate students and teachers. The idea of halophosphate phosphors has assumed even more meaningful in the overall scheme of scientific progress. The luminescent material known as phosphor convert energy into electromagnetic radiation, usually in the visible energy range. Facile combustion syntheses of novel halophosphate phosphors using easily available starting materials were investigated. There are large number of mixed anion phosphates known to chemists and geologists. However, no luminescence measurements are available on these halophosphate materials. I presented the exact formulas for calculations and conditions required to make all of the phosphors known at that time. Each formula was the result of many hours of experimentation to optimize the final phosphor composition. Because I believe that one needs to know what the history of any given subject entails, I have retained much of the material presented in the present book. I have enjoyed preparing this book and hope that you find reading it both profitable and enlightening.
