Development of simultaneous multivariate measuring method by means of fast-responding bi-luminophore-pressure sensitive dot array sensor

在阳极氧化铝（AA）衬底上研制了一种用于非定常流场测量的快速响应双发光团压敏点阵列传感器。我们采用喷墨印刷方法在AA基板上形成PSP和TSP的隔离点阵列，以防止两个发光团之间的干扰。每种染料选择合适的溶剂，形成均匀、高发光强度、高灵敏度的斑点。所制备的双发光基团AA-PSP可以同时测量压力和温度，并将温度效应从0.97% /℃（无温度校正）降低到0.02% /℃（有温度校正）。从压力上升90%到压力阶跃变化的压力响应时间为64微秒，与传统的AA-PSP相同。

A fast response bi-luminophore pressure-sensitive dot array sensor has been developed on an anodized aluminum (AA) substrate for unsteady flow measurements. We have applied the isolated dot arrays of PSP and TSP formed on an AA substrate by an inkjet printing method to prevent interference between the two luminophores. Suitable solvent was chosen for each dye to form the dots with uniform and high luminescence intensity, and high sensitivity. The created bi-luminophore AA-PSP could simultaneously measure pressure and temperature and could reduce the temperature effect from 0.97 %/degree C (without temperature correction) to 0.02 %/degree C (with temperature correction). It showed a pressure response time of 64 micro sec at 90 % pressure rise to a step change of pressure, which is in the same range with a conventional AA-PSP.
