Yet there are serious ecological concerns regarding toxicity to the environment and living organisms once devices made with it are discarded; PLZT contains around 60 per cent of lead (by weight). The search is on to find lead-free replacements for PLZT.<\/p>\n<p><!-- Link: <a href=\"https:\/\/phys.org\/news\/2019-02-ceramic-greener-optical-devices.html\">https:\/\/phys.org\/news\/2019&#45;02-ceramic-greener-optical-devices.html<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A lead-free ceramic that could be used in applications ranging from optical sensors and switches to creams for protecting against ultraviolet (UV) light has been developed by A*STAR researchers.
