  In this study, we describe a novel approach to quantum phenomena of the
generalized electromagnetic fields of dyons with quaternionic analysis.
Starting with quaternionic quantum wave equations, we have established a
quantized condition for time coordinate that transforms microscopic to
macroscopic fields. In view of classical electromagnetic field equation, we
propose a new set of quantized Proca-Maxwell's equations for dyons.
Furthermore, a quantized form of four-currents densities and the quantized
Lorentz gauge conditions, respectively for electric and magnetic potentials of
dyons are obtained. We have established the new quantized continuity equations
for electric and magnetic densities of dyons which associated with a torque
density result from the two spin states. The quantized Klein-Gordon like field
equations and the unified quaternionic electromagnetic potential wave equations
for massive dyons are demonstrated. Moreover, we investigate the quaternionic
quantized relativistic Dirac field equations for massive dyons, which indicated
that there will be the existence of antiparticle of dyons called antidyons.
