A novel blue-emitting phosphor of Eu(2+)-activated NaMgPO(4) was prepared by combustion-assisted synthesis. Sodium dihydrogen phosphate and magnesium nitrate were used as the source of Na, P and Mg, respectively. The ratios of magnesium and phosphorus components that were dissolved into the combustion solution were changed from 1:1 to 1:1.3. Their effect on the crystallinities and photoluminescence spectra of the phosphor particles were investigated. The post-heated phosphor particles had a broad excitation wavelength that ranged from 240 to 410 nm. The phosphor particles prepared from the combustion solution with a 1:1.2 ratio of magnesium to phosphorus had maximum emission intensity under ultraviolet excitation. The effect of doped Eu(2+) concentration on the emission intensity of PO₄:Eu(2+) was also investigated.
采用燃烧辅助合成法制备了 Eu(2+)-激活的 NaMgPO(4)新型蓝色发光体。磷酸二氢钠和硝酸镁分别用作 Na、P 和 Mg 的来源。将溶解在燃烧溶液中的镁和磷组分的比例从 1:1 改变到 1:1.3。研究了它们对荧光粉颗粒结晶度和光致发光光谱的影响。后加热的荧光粉颗粒具有从 240 到 410nm 的宽激发波长。在紫外激发下，由镁磷比为 1:1.2 的燃烧溶液制备的荧光粉颗粒具有最大的发射强度。还研究了掺杂 Eu(2+)浓度对 PO₄:Eu(2+)发射强度的影响。
