The arrival of thermal pulses propagating through glass is retarded at high excitation energies. The retardation time is approximately proportional to the excitation energy, suggesting characteristics of nonequilibrium phonons at high densities in glass. The late time signal decays approximately exp
This paper presents the application of quantitative image analysis for the description of morphological properties of nanocomposites with YAG:Tb. Fracture images of YAG:Tb and nanocomposites were obtained using a high-resolution scanning electron microscope (HR-SEM) and atomic force microscopy (AFM)
The exponential decay of phonon intensity observed in both experiments and simulations for the quasidiffusive propagation regime reflects the elastic and inelastic scattering process of high frequency phonons. In search of the predicted quasidiffusive behaviour, we have removed the contact with liqu
