(Received 8 April 2008; accepted 9 June 2008; published online 27 June 2008)

We demonstrate the thermal tunability of the emission of polymer embedded in microcavities. The large thermo-optic coefficients of a conjugated polymer is combined with the possibility to tailor the emission properties by means of cavities acting as optical filters. Both the transmission and the photoluminescence spectra of the polymer in cavities can be finely tuned with slopes up to about −0.2 nm/°C. Such an effect could be exploited to realize thermally tunable organic light-emitting devices for optical communication or sensing applications.

Figures (click on thumbnails to view enlargements)

FIG.1
Upper plot: room temperature PL spectrum of the conjugated polymer (continuous line, vertical scale on the right) and transmission spectrum of the cavity (dotted line, vertical scale on the left). The capital letters label the main features. Lower plot: transmission spectrum compared to room temperature PL spectrum of the polymer embedded in the cavity (continuous line, vertical scale on the right). The roman numbers label the peaks of the PL spectrum: the association among some PL peaks and the peaks due to the transmission of the cavity (I-A, II-B, IV-C, VI-D) is evident.

FIG.2
Transmission spectra of the cavity as a function of the temperature: the continuous line plot shows the reference spectrum measured at room temperature (about 25 °C), the dotted plots represent the spectra recorded increasing T with steps of 10 °C until the final value of 65 °C. The insets zoom in the regions around the peaks on a normalized plot, the arrows in the insets indicate increasing temperatures.

FIG.3
PL spectra of the polymer embedded in the cavity for various temperatures: the continuous line plot shows the reference spectrum measured at room temperature (25 °C), the dotted plots represent the spectra recorded increasing T with steps of about 10 °C until the final value of 60 °C. The insets zoom in the region around the peaks, the arrows in the insets indicate increasing temperatures.

Tables

Table I. Wavelength shift of the peaks derived from the transmission and the PL spectra. The peaks are defined by the label given in the previous graphs (first column and third column) and the measured wavelength shifts with the temperature are reported in the second and fourth column. Corresponding peaks from transmission and PL spectra (the ones on the same rows in the table) have the same shift within the standard deviation.
