The Vicker’s hardness results show that the hardness increases slightly with increase of Eu3+ doped ZBB glasses.
The transmission spectra show that the ZBB glasses exhibit maximum transmission in visible region for 1.0 mol % Eu3+ doped glasses.
The intensities of emission bands increases with increase of Eu3+ concentration, due to the asymmetry around the Eu3+ in the ZBB glass host. The strongest peak was found at 613 nm (red emission).
The lifetime curve exhibited single exponential nature in all the glasses and the measured lifetime increases with increase of Eu3+ concentration.
