The calcium cyanamide (CaCN 2 ) reduction route was applied for the synthesis of the Eu 2+ (2 at%)-activated CaAlSi 1+2x N3+2x Ox (x = 0–1) phosphors, and the impact of oxygen content on photoluminescence properties was investigated. The relationship of crystallographic parameters of the solid solution and oxygen content were also studied. All of the samples showed a broadband excitation covering the range from UV to visible region, revealing that this phosphor was a potential candidate for the phosphor-converted white LEDs. Under the UV/blue excitation, this series phosphor gave the emission peaks varying from 585 to 641 nm. The shifting behavior was dominantly contributed to the second luminescent center formed by the introduction of oxygen into nitride phosphors.

【期刊论文】Acetate reduction synthesis of Sr 2 Si 5 N8 :Eu 2+ phosphor and its luminescence properties

A novel synthesis method was developed for the efficient red phosphor, Eu 2+ -activated Sr 2 Si 5 N8 ,by employing the strontium acetate as both the reducing agent and strontium source. The phase purity of final product was strongly dependent on the heating rate of the precursors. Sr 2 Si 5N 8 :Eu 2+ (2 at%) phosphor presented a broadband excitation spectrum in the range 300–500 nm, matching well with the blue emission (400/460 nm) of current InGaN light-emitting diodes (LEDs). The red emission peaking at 619 nm gave the relatively high (about 155%) intensity compared with the Y 3 Al 5O 12 (YAG) (P46-Y3) standard phosphor. In addition, the saturated chromatic coordinates (0.638, 0.359) allowed it a promising candidate as a red phosphor in white LEDs application for illumination or display.
