摘要

A highly intense reddish-orange and blue emitting borate phosphors YAl_3(BO_3)_4:Sm~(3+) and LaMgB_5_ O_(10):Ce~(3+) have been synthesized by a combustion synthesis method using urea as a fuel. Their luminescent properties have been studied over the 200-450 nm excitation range. The excitation and emission spectra of these phosphors were measured by a HITACHI F-7000 fluorescence spectrophotometer. The emission spectrum of Sm~(3+) in YAl_3(-BO_3)_4 phosphor monitored for 402 nm excitation composed of 564, 600, and 648 nm emission peaks, and the excitation spectra monitored at 600 nm emission shows peaks at 345, 362, 375,402, 421 and 445 nm. The emission spectrum of Ce~(3+) in LaMgB_5O_(10) phosphor exhibits a symmetrical band centered around 430 nm and excitation spectra monitored at 430 nm emission shows peaks at 272, 326 and 372 nm. The phosphors YAl_3(BO_3)_4:Sm~(3+) and LaMgB_5O_(10):Ce~(3+) can be a promising red and blue-emitting phosphor for UV LED applications.
