本工作的目的是开发一种在近紫外光激发下发射白色光的单相荧光粉，以应用于白色发光二极管。我们的基本原理是采用一种含有稀土非中心对称配位的基质，因此可以增强近紫外范围内的f-吸收。实际上，YGa 3（BO 3）（4）是这样的基质，其中Y 3+处于扭曲的三棱柱中，并且可以被各种稀土元素取代。研究了Dy ~（3+）和Tm ~（3+）在Y_1-xDy_xGa_3（BO_3）（4）（0
The purpose of this work is to develop a single-phase phosphor emitting white light under the excitation of near LTV light, targeted at the possible application in white light emitting diodes. Our rationale is to employ a host containing noncentrosymmetric coordination sites for rare earth, therefore the f-f absorptions in the near UV range could be enhanced. Indeed, YGa3(BO3)(4) is such a host where Y3+ is in a twisted triangular prism and could be substituted by various rare earth elements. The photoluminescence of Dy3+ and Tm3+ were investigated in Y1-xDyxGa3(BO3)(4) (0
