Abstract

The Ca _1-xMg _xAI ₁₂0 ₁₉:Mn ⁴⁺ compounds were prepared by liquid phase precursor (LPP) methods for use in white light emitting diodes (LEDs) based on nano red phosphor. The effect of adding Mg element on the relative emission characteristics of Ca _1-xMg _xAI ₁₂O ₁₉Mn ⁴⁺ is discussed in terms of the charge compensation effect. The LPP synthesis, the relative emission intensity of Ca _1-xMg _xAI ₁₂0 ₁₉:Mn ⁴⁺ containing ratio of 0.05 MgO was approximately 70% higher than that of the LPP synthesized Ca _1-xMg _xAI ₁₂O ₁₉Mn ⁴⁺ red phosphor. These results indicate that the use of an appropriate LPP synthesis improve excellence the luminescent efficiency, particularly for the samples prepared with the optimized firing temperature of 1450 °C for 1 hour.
