Abstract

The development of photoluminescent (PL) properties in graphitic carbon nitride (g-C3N4) has been limited by their short PL wavelength. Herein, we synthesized tunable multi-color emissive cyanuric acid-supported g-C3N4 materials (CNS) via a one-pot microwave-assisted method using urea and thiophene-3,4-dicarboxylic acid (TDC) as starting materials. By varying the TDC amount, the solid-state emissive color of CNS samples can be manipulated from blue to orange-red. The incorporation of thiophene ring into the g-C3N4 framework during microwave synthesis enlarges the π-conjugation system, narrowing the band gap from 3.94 to 1.91 eV, as verified by the DFT calculations. The hydrogen-bond networks from cyanuric acid-supported g-C3N4 improves the framework crystallinity, enabling the high emission efficiency (quantum yields up to 0.27). These properties make CNS highly suitable for multi-color light-emitting diodes (LED) applications, particularly in WLEDs with chromaticity coordinates (0.341, 0.359). Additionally, this study pioneers the use of CNS as a solid-state fluorescent probe for Fe3+, expanding its optical application fields. Our findings suggest significant potential for CNSx materials in advanced LED lighting solutions, with broad applicability in illumination, information encryption, and anti-counterfeiting.

用于多色发光二极管和固态荧光传感的高发光三聚尿酸支持的氮化碳杂化体
石墨氮化碳(g-C3N4)的光致发光(PL)性能的发展受到其短的PL波长的限制。本文以尿素和噻吩-3,4-二羧酸(TDC)为原料,采用一锅微波辅助法制备了可调多色发射型三聚氰尿酸负载g-C3N4材料(CNS)。通过改变TDC的量,可以使CNS样品的固态发射色由蓝色变为橙红色。在微波合成过程中,噻吩环加入到g-C3N4框架中,扩大了π共轭体系,将带隙从3.94缩小到1.91 eV,这得到了DFT计算的验证。氰尿酸负载的g-C3N4的氢键网络提高了骨架的结晶度,使发射效率高(量子产率高达0.27)。这些特性使得CNS非常适合多色发光二极管(LED)应用,特别是在色度坐标(0.341,0.359)的wled中。此外,本研究开创了利用CNS作为Fe3+固态荧光探针的先机,拓展了其光学应用领域。我们的研究结果表明,CNSx材料在先进的LED照明解决方案中具有巨大的潜力,在照明、信息加密和防伪方面具有广泛的适用性。
