After lord Khoat's death, an overpowered mandarin named Trương Phúc Loan changed lord Khoat's will to make Luan's younger brother Nguyễn Phúc Thuần to be the next ruler.
Luan was buried at Cơ Thánh Tomb, located at Cư Chánh, Hưng Thuỷ, Thừa Thiên Huế.
Later, his son Nguyễn Phúc Ánh posthumously gave him the title Nhân Minh Cẩn Hậu Khoan Dụ Ôn Hòa Hiếu Khang Hoàng Đế (仁明謹厚寬裕溫和孝康皇帝).
Nguyễn Phúc Luân had three wives: Nguyễn Thị Hoàn - mother of Đồng, Ánh (Gia Long), Điển, and Ngọc Tú; Hoàn's elder sister - mother of Hạo, Mân, Ngọc Du, Ngọc Tuyền and one son who died as an infant; and Tống Thị Diên - mother of Ngọc Uyển.
All of them later were killed in battle with the Tây Sơn, except Nguyễn Phúc Ánh.
