Results and Discussion Fig. 1 is the emission spectra of glasses doped with the active ions.
Table 1 shows fluorescence lifetimes of the active ions doped Ge25Ga5Sb5Se65 glasses.
The immediate stage where the donor-donor interaction becomes important, the decay follows an exponential behavior at a rate determined by the following equation: 1/τm = 1/τ0 + VCDyCTm (1) Where τm is measured lifetime, τ0 is the lifetime of Tm3+ single-doped sample, V is a constant related to transfer constants, CDy and CTm represent Dy 3+ and Tm3+ concentrations, respectively.

The lengths and angles of the entering and exiting clothoid arcs are the same, as can be observed in Fig. 1.
The acceleration of this particular model has a very high value and after only 1 second of full reverse the car already passed 5 meters.

The morphology of γ' phases was cubical and well coherent with the γ-matrix without any precipitation, as shown in Fig.1.
Fig. 1 The microstructure of the alloy after standard heat treatment Fig.2 shows the morphological evolution of γ' particles when aging at 1050℃ for different times.
Table 1 lists the effect of aging time on particle size a and the average radius r (r=a/2) of γ' phase.
The volume fraction of TCP phases decreased obviously when aged at 1150℃ compared to that for 1050℃, References [1] R.C.
