Growth, luminescence, dielectric and photoconductive properties of ?-Nickel sulphate hexahydrate for UV filter applications
Abstract
In the present study, the <001> directed alpha Nickel Sulphate hexahydrate (NSH) crystals was grown by Sankaranarayanan Ramasamy (SR) Method, mainly because of the required (0 0 l) face for device performances. Superior characteristics of photoluminescence and dielectric properties of SR method grown NSH single crystal were observed. In addition the violet luminescence, dielectric and negative photoconductivity behavior of the NSH crystal was discussed.
