It is a good deed to give Sadaqah on your father's behalf and dedicate the reward of endowing the Mus-hafs to him, may Allah accept that from you. It is permissible to write "This is Waqf" to notify people, lest they do anything that negates this fact, but it is better not to write his name. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
