Alq3 or α-NPD films sandwiched between aluminum (Al) films [Al/(Alq3 or α-NPD)/Al] were deposited by vacuum evaporation, as commonly used materials in OLED devices.
Figure 6 shows the thermo-reflectance signals of Al/α-NPD/Al three-layered films.

Moreover, in an ITO/PVK/Tb(GFLX)3Phen/Al device, Tb3+ ion can be excited by intramolecular ligand-to-metal energy transfer process.
The experiment result shows the complex is stable, and their PL and EL properties were systematically studied by using the complex as emissive material.

Yeh et al. [8] found that the thermal decomposition of these materials is high temperature range than PMMA matrix, which confirms the enhancement of thermal stability of reinforced PMMA.
These observations are in good agreement with Yeh et al. [8] whereby, the thermal decomposition of these materials are at higher temperature than PMMA matrix, which confirms the enhancement of thermal stability of reinforced PMMA.
This is in agreement with Rodney et al. [17] who reported that the DSC examination of PMMA denture base and appears two downward steps in the DSC curve that represent Tg and residual polymerization (unreacted monomer).

At ES = 15 J/cm2 (molten Al surface layer, solid Ti film), the Ti concentration in the Al surface layer decreases to 2.7 wt% after 50 pulses (Fig. 1a, curve 2).
At ES = 20 J/cm2 (surface-molten Ti–Al system), the Ti concentration in the Al surface layer is 2.3 wt% even after 3 pulses.
