摘要：
This paper reports an up-conversion emission in violet (408 nm) from Nd3+-doped 93SiO(2):7TiO(2): 20AlO(1.5) glasses synthesized by the sol-gel process. Upon excitation at 583 nm (I-4(9/2)-->(4)G(5/2)), a bright violet up-conversion emission at 408 nm has been observed. The behavior of the up-conversion luminescence has been compared with that of the normal luminescence at both 408 and 1064 nm. The results show that while no concentration quenching for up to 2 mole Nd content is observed for the up-conversion emission, such an effect can be observed for the normal luminescence cases. Although the up-conversion luminescence has a shorter lifetime and weaker intensity, it is of use to the development of sol-gel glass-based waveguide lasers operating at the violet wavelength.
