A series of Sr2GdNbO6:xEu3+ (x=0.04-0.12) red phosphors were prepared by a high-temperature solid-phase method, and the target products were characterized by X-ray diffraction, UV-Vis spectrophotometry and fluorescence spectroscopy. The results show that the synthesized phosphor has a monoclinic crystal structure with the space group P21/c. The structural analysis indicates that doped europium replaces Gd3+ ion in the matrix Sr2GdNbO6 with the chemical state of Eu3+ ion, thus forming a single crystal structure phosphor. Sr2GdNbO6:Eu3+ phosphor exhibits a red-orange emission under dual-wavelength excitation of blue light λex of 468 nm and near-ultraviolet light λex of 395 nm, and the main emission peaks are centered at wavelengths of 622 nm and 593 nm, which belong to the 5D0→7F2 and 5D0→7F1 energy level transitions of Eu3+, respectively. When the doping amount (x) of Eu3+ is 8%, its luminescence quantum efficiency for blue light excitation reaches the maximum value of 16%. Based on the analysis and comparison of the temperature (295-568 K) effect on the emission intensity and quantum efficiency under dual-wavelength excitation, the phosphor has a high luminescence quantum efficiency under the excitation of blue light λex of 468 nm and a higher thermal stability. Under the excitation of blue light, the average fluorescence decay lifetime of the sample Sr2GdNbO6: 0.08Eu3+ is 0.841 ms, the color coordinates are (0.648, 0.368), and the luminescence purity reaches 93%. This phosphor is a kind of red fluorescent material with the dual-wavelength response for a promising potential application.

针对目前钙钛矿型红色荧光粉热稳定性较差的问题,以带隙和结构可调变的双钙钛矿型Sr2GdNbO6为基质、Eu3+为激活离子,采用高温固相法成功制备双钙钛矿型Sr2Gd1-xNbO6:xEu3+(x=0.04~0.12)红色荧光粉,通过X射线衍射、紫外-可见分光光度和荧光光谱分析对目标产物进行表征。结果表明:合成的荧光粉具有单斜晶体结构,其空间群为P21/c。结构分析表明:掺杂的铕以Eu3+的化合态取代了基质Sr2GdNbO6中的Gd3+,形成了单一晶体结构的荧光粉。Sr2Gd1-xNbO6:xEu3+荧光粉在蓝光λex=468 nm和近紫外λex=395 nm双波长激发下均呈现红橙色发射光,主发射峰中心波长位于622 nm和593 nm处,分别归属于Eu3+的5D0→7F2和5D0→7F1能级跃迁。当Eu3+的掺杂量为x=8%(摩尔分数),其蓝光激发的发光量子效率达到最高值16%。对比分析了双波长激发下温度(295~568 K)对其荧光强度和发光量子效率的影响。结果表明:蓝光λex=468 nm激发下该荧光粉不仅发光量子效率高,而且其耐热稳定性也更高。在蓝光激发下样品Sr2GdNbO6:0.08Eu3+的荧光衰减平均寿命为0.841 ms,色坐标为(0.648、0.368),发光色纯度达到93%,是一种具有应用潜在前景的双波长响应的新型红色荧光材料。

针对目前钙钛矿型红色荧光粉热稳定性较差的问题,以带隙和结构可调变的双钙钛矿型Sr2GdNbO6为基质、Eu3+为激活离子,采用高温固相法成功制备双钙钛矿型Sr2Gd1-xNbO6:xEu3+(x=0.04~0.12)红色荧光粉,通过X射线衍射、紫外-可见分光光度和荧光光谱分析对目标产物进行表征。结果表明:合成的荧光粉具有单斜晶体结构,其空间群为P21/c。结构分析表明:掺杂的铕以Eu3+的化合态取代了基质Sr2GdNbO6中的Gd3+,形成了单一晶体结构的荧光粉。Sr2Gd1-xNbO6:xEu3+荧光粉在蓝光λex=468 nm和近紫外λex=395 nm双波长激发下均呈现红橙色发射光,主发射峰中心波长位于622 nm和593 nm处,分别归属于Eu3+的5D0→7F2和5D0→7F1能级跃迁。当Eu3+的掺杂量为x=8%(摩尔分数),其蓝光激发的发光量子效率达到最高值16%。对比分析了双波长激发下温度(295~568 K)对其荧光强度和发光量子效率的影响。结果表明:蓝光λex=468 nm激发下该荧光粉不仅发光量子效率高,而且其耐热稳定性也更高。在蓝光激发下样品Sr2GdNbO6:0.08Eu3+的荧光衰减平均寿命为0.841 ms,色坐标为(0.648、0.368),发光色纯度达到93%,是一种具有应用潜在前景的双波长响应的新型红色荧光材料。

A series of Sr2GdNbO6:xEu3+ (x=0.04-0.12) red phosphors were prepared by a high-temperature solid-phase method, and the target products were characterized by X-ray diffraction, UV-Vis spectrophotometry and fluorescence spectroscopy. The results show that the synthesized phosphor has a monoclinic crystal structure with the space group P21/c. The structural analysis indicates that doped europium replaces Gd3+ ion in the matrix Sr2GdNbO6 with the chemical state of Eu3+ ion, thus forming a single crystal structure phosphor. Sr2GdNbO6:Eu3+ phosphor exhibits a red-orange emission under dual-wavelength excitation of blue light λex of 468 nm and near-ultraviolet light λex of 395 nm, and the main emission peaks are centered at wavelengths of 622 nm and 593 nm, which belong to the 5D0→7F2 and 5D0→7F1 energy level transitions of Eu3+, respectively. When the doping amount (x) of Eu3+ is 8%, its luminescence quantum efficiency for blue light excitation reaches the maximum value of 16%. Based on the analysis and comparison of the temperature (295-568 K) effect on the emission intensity and quantum efficiency under dual-wavelength excitation, the phosphor has a high luminescence quantum efficiency under the excitation of blue light λex of 468 nm and a higher thermal stability. Under the excitation of blue light, the average fluorescence decay lifetime of the sample Sr2GdNbO6: 0.08Eu3+ is 0.841 ms, the color coordinates are (0.648, 0.368), and the luminescence purity reaches 93%. This phosphor is a kind of red fluorescent material with the dual-wavelength response for a promising potential application.
