Iznik ceramics/pottery is one of the correct names, but Kütahya ceramics is more common nowadays. In addition, you can simply use the Turkish word çini to buy one in Turkey.
The capital of ceramics in Turkey is Kütahya Province. They are most probably made in Kütahya. Production in Iznik (Bursa Province, Turkey) almost died after 18th century.
The plate on the second image approximately costs €15.
Extra information: Since tulip and clove flowers are commonly used on Turkish ceramics, the plate on the second image is more recognizable for me.
