This book reports the basics of hybrid phosphor materials, their synthesis routes and their special properties and characterization techniques. It gives the reader information about the natural origins and development of hybrid materials, which are developed by combining inorganic and organic species in one material interface-determined materials. The book provides a general classification of hybrid materials, wherein inorganic materials modified by organic moieties are distinguished from organic materials or matrices modified by inorganic constituents. It gives a focus to the functionalization of organic materials by inorganic additives. The application areas covered include optoelectronic field, sensor applications, biological and environmental applications.

Upconversion Nanophosphors provides detailed information about various lanthanide-based upconversion nanoparticles and their application in different fields. It will also help solve fundamental and applied problems of inorganic phosphor materials showing upconversion behavior, as well as generate innovative ideas related to the application of inorganic phosphor materials. This book will prove to be an invaluable reference work for scientists, engineers, industrial experts, and masters and PhD students working in the field of upconversion and materials science.

In the present book some simple and sensitive spectrophotometric methods for determination of drugs in pharmaceutical formulations and in biological samples have been described. The methods are based on the use of chromogenic reagents, redox reactions, solvent extraction and solid phase extraction techniques. The methods for validation of developed methods have also been described. The drugs for which methods have been described are -methyldopa, sulphonamide derivatives, lamivudine, nimesulide, nicorandil, olanzapine, and phenothiazine derivatives."
