Well, not sure if any equation is known as de Broglie equation.
But if there is one it is his proposed relation for the the wave length of a particle in motion.
wavelength = h/p where h is Plank's constant and p = mv is the linear momentum of the particle of mass m moving with a velocity v.

de Broglie's equation (1925) - states that every body of linear momentum p has an associated wave character of wavelength given by h/p where h is Planck's constant.
When postulated it was not clear what was the nature of this "matter wave". However, Schrodinger illuminated matters in this respect with his equation about a year later.
Evidence in support of de Broglie's relationship may be obtained from experiments such as that of Davisson and Germer in which the diffraction of electrons was observed by the ordered rows of atoms in a piece of nickel metal. In order for diffraction to occur the wavelength of the electrons has to be of the same order as the separation between the rows of nickel atoms.
De Broglie's equation shows this to be so.

Definition: an equation used to describe the wave properties of matter, specifically, the wave nature of the electron: l = h/mv, where l is wavelength, h is Planck's constant, m is the mass of a particle, moving at a velocity v. de Broglie suggested that particles can exhibit properties of waves.

de-Broglie's wave equation regarding dual nature of matter put forward on the year 1923 modifies the statement light has dual nature of Einsten's by stating that every matter exhibhit both particulate and wave nature.
i.e, L=h/mv where h is plancks constant, L is wavelength, mis mass and v velocity value of h is 6.63x10*-34.it is obtained by following steps
E=mc*2=hc/L
his two page article regarding dual nature of matter really shook the world . later two scientists Germer and Davisson proved it by carrying out diffraction experiments with a fast moving beam of electrons. Later Louis de-broglie, Germer and Davisson shared nobel prize for their work

The de Broglie equation is the universal relationship between wavelength, l, (wave nature) and momentum, p, (particle nature).
l = h/p
The constant of proportionality, h, is Planck's constant

wavelength=h/p
where h = Planck's Constant
p = momentum = mass* velocity

francis de brogile was travelling with einstien on a train discussed about combining particle and wave nature of matter,to describe partice nature of matter he had einstiens mass -energy relationship E=mc*c;where m is the mass of the particle and c is the velocity of light;to describe wave nature of particle he had eqn E=h*r(read h*new,r for frequency of particle),E=h*c/lambda
equating and generalising we get de brogile equation lambda=(h/m*v)

L=h/p
L denotes the wavelength of the light rays
h is the constant-PLANCKS CONSTANT
P IS THE MOMENTUM ATTAINED

wavelength=h/p
h=plank's constant=6.625*10^-34
p=momentum
this eq can be used to all matter
