AbstractThin films of M[SUB2]B[SUB5]O[SUB9]Cl:Eu (M = Ca, Sr, Ba) were prepared on glass substrates using spray pyrolysis. Blue cathodoluminescence due to the abnormal reduction of Eu[SUB3+] → Eu[SUB2+] was obtained by annealing films in air. The cation of the host lattice was found to affect the effectiveness of the reduction process, which could result in influencing the emission band. By selecting types and composition of alkaline cation, it was possible to tune the dominant emitting wavelength between 435 to 465 nm. Activation of the films occurred at temperatures suitable for the use of glass substrates. © 2003 American Institute of Physics.
