DNA系统中的光放大是未来高效、紧凑的光子器件的一项有前途的技术。由于半花菁染料的高荧光特性是由与DNA或DNA复合物的相互作用引起的，因此它们对基本光学性质的影响在用两种方法制备的溶液和固体膜中进行了阐述。吸收光谱和荧光光谱的研究结果表明，最强的发光是通过与DNA-CTMA（十六烷基三甲基铵）的相互作用而不是直接与裸DNA偶联而实现的。比较了两种方法制备的薄膜的激光性能，表明这种新开发的浸渍方法提供了高掺杂样品具有更好的强度，阈值和耐久性的性能。
Light amplification in DNA systems is a promising technique for efficient and compact photonics devices in the future. Since highly fluorescent properties for hemicyanine dyes are caused by the interaction with DNA or a DNA-complex, their effects on basic optical properties were elaborated in phases of solution and solid films prepared with two methods. Results of absorption and fluorescence characteristics showed that the strongest light emission was achieved by the interaction with DNA-CTMA (cetyltrimethylammonium) rather than direct coupling to bare DNA. Laser performance was compared for films prepared with two means, indicating that this newly developed immersion method provided highly doped samples with better performance in intensity, threshold value and durability.
