Zinc sulphide nanoparticle with manganese doped (2-6%), (ZnS: Mn2+) have been investigated. These Mn2+ doped ZnS nanoparticles have been synthesized by chemical precipitation method at room temperature. So-prepared Mn2+ doped ZnS nanoparticles then characterized by using X-ray diffraction (XRD), Scanning electron microscope (SEM), UV-Vis spectrophotometer, Photoluminescence (PL) using F-2500FL Spectrophotometer. The size of the particle is found to be in 5.24-5.64 nm range. The value of optical band gap has been found to be in range 3.87-4.46 eV. Room temperature photoluminescence (PL) spectrum of the undoped sample exhibit a blue emission peaked at 375 nm under UV excitation. The Mn2+ -doped sample exhibits a yellow emission peaked at 577 nm..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
