# Mercury: Not enough atmosphere. So hot that most of the gas can escape. # Venus: Has some ozone in its atmosphere, but not much. Almost no free oxygen. Most ozone found high above the sulfuric acid clouds. Ozone requires replenishment by UV-C, and Venus' atmosphere is so thick, UV-C does not make it far. # Earth: Ozone layer. Moon: No detectable ozone (and not much oxygen). # Mars: Some ozone, almost no free oxygen (so ozone must be formed from "shattered" CO2). # Jupiter's moon Ganymede has some ozone, made almost entirely by charged particle bombardment due to Jupiter's magnetic field. No other planets seem to have any appreciable ozone in their atmospheres.
We are not able to image exoplanets well enough to know if there is significant ozone on planets orbitting distant stars. Yet. So it looks like the biggest players as to whether there is an ozone layer, are: # Plenty of free oxygen molecules (meaning moderate temperatures too), and # Enough UV-C from the Sun to break apart oxygen molecules, so that some ozone can form. Oxygen is extremely reactive. Any oxygen present quickly reacts to form other compounds. However, Earth's plants continually free up oxygen in their process of respiration (using sunlight to break up carbon dioxide, keeping the carbon and freeing the oxygen), thus keeping Earth's atmosphere heavily laden (21%) with oxygen.
If the plants died, the oxygen would be quickly reabsorbed into compounds and our atmosphere would become unbreathable to humans and animals, resembling Venus in temperature (+400 Celsius).

Why are ozone layer on the earth in spite other planets?
Unfortunately, the question is hard to understand. Ozone is a form of oxygen. There is no known ozone layer on other planets in the solar system.
