英文摘要:
Pr3+/Ho3+ co-doped fluorozirconate glasses were prepared and their luminescence properties studied. Blue, green and red luminescence in the wavelength region of 470-750 nm were achieved in these glasses under 443 nm light-emitting diode (LED) excitation. The ratio of Pr3+-Ho3+ was changed in order to determine the appropriate combination for realizing color-controlled white LEDs. The color temperature of the white light can be adjusted by changing the LED-excitation wavelength or the ratio of the Ho3+/Pr3+ ions. Thus, Pr3+/Ho3+ co-doped fluorozirconate glasses are potential materials for use in white LEDs. (C) 2015 Elsevier B.V. All rights reserved.
