BaMgAl 10 O 17 :Mn 4+4+, K phosphor is synthesized by solid state method in air Emission spectrum in the region from 600 to 780 nm is observed with the strong emission peak at ~ 663 nm owing to the 2E → 4A2 transition of Mn4+ ions. Excitation spectrum in the range of 220 - 520 nm monitored at 663 nm is shown with three excitation band peaks ~ 288, 360, and 450 nm T he emission intensity of BaMgAl 10 O 17 :Mn 4+ phosphor is enhanced 1. 6 times by co doping K ion The luminous mechanism is explained by Tanabe-Sugano diagram of Mn 4+ ion.
Phosphors, Mn4+ ion, Red-emitting, Charge compensation.

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.
