摘要：

HoxY1-xAl3(BO3)(4) and PrAl3(BO3)(4) crystals have been grown from high-temperature solutions. Holmium segregation coefficients ranged from 1.08 to 1.40. Strong visible and near-infrared luminescence from Ho3+ and Pr3+ was obtained in the crystals with only weak-concentration quenching. Spectral evidence of energy transfer among Ho3(+) ions was also observed. The simultaneous observations of low-concentration quenching and Ho3+-Ho3+ energy transfer suggest that YAl3(BO3)(4) is a suitable host lattice for high-efficiency rare-earth energy transfer and sensitization schemes.
