A new class of praseodymium‐doped ceramics simultaneously displays electrostriction (the conversion of electrical energy into mechanical energy), mechanoluminescence, and electroluminescence. For example, red‐light emission is produced upon compression (see Figure). These environmentally friendly materials may find application in multifunctional sensors or devices.
