RELATION BETWEEN DEBYE TEMPERATURE AND PARTICLE SIZE OF NANOMETER-SIZED SILVER PARTICLES
纳米银颗粒的Debye温度与粒径的关系

Debye temperature of nanometer-sized silver(n-Ag) particles was studied by the method of the double temperature X-ray diffraction. It was found that values of most specimens were higher than that of the bulk-Ag. And there existed a critical size.When the particle size was smaller than the critical value, the smaller the particle size was, the lower its became. To the specimen with larger particle size than the crucial size, its became smaller than that of the specimen with the crucial size.It was also deduced that the relation between and d of n-Ag particles could be given as:which explains the experiment result reasonably.
