采用溶胶-凝胶法制备了Ru(bpy)32+（bpy-2,2′-联吡啶）玻璃样品。得到了钌配合物在15 ~ 340 K温度范围内的电子吸收和发射光谱。在玻璃中掺入配合物会导致发射最大值的蓝移。所获得的含Ru(bpy)32+的玻璃样品通过将磷光强度与温度联系起来作为温度传感器。讨论了光电式热传感器的实验装置。
Samples of glasses containing Ru(bpy)32+(bpy-2,2'-bipyridine) have been prepared by the sol-gel method. Electronic absorption and emission spectra of the entrapped ruthenium complex have been obtained in various temperatures ranging from 15 to 340 K. Incorporation of the complex in the glass results in the blue shift of the emission maximum. The obtained glass samples containing Ru(bpy)32+have been utilized as temperature sensors via relating the phosphorescence intensity to temperature. The experimental setup of the thermosensor (optode) is discussed.
