A new high calcium aluminoborate glass with a simple composition of CaOAl2O3B2O3 ( was synthesized and investigated detailedly by XRD, FT IR, UV, DSC, and PL analysis methods. The results showed that this kind of glass matrix has a good thermal stability, fine transmittance in visible light, low absorption in VU wavelength, and fine ability of molten rare earth oxide. The luminescence of Tb3+ doped glass phase showed the excitation peak s centred at 378 nm and 486 nm are assigned to the transitions of 7F66→(5D3,5G6) and 7F66→6D4 of Tb3+, respectively. The optimum doping concentration for Tb3+ was determined to be 15.6 mol% when excited by 378 nm and the luminescence of Tb3+ straight increase with the Tb3+ con centration up to 21.9 mol% without con centration quenching when excited by 486 nm The CIE chromatic coordinates, dominant wavelengths, and color purity values of Tb3+ doped glasses were determined. The effects of Si4+ and Li doping on the emission intensities of Tb 3+ were investigated. Due to this Tb3+ doped calcium aluminoborate glass can be excited by both ultraviolet and blue light, it may be an excellent luminescence material for LEDLED..

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.
