Using Variables When Creating A Database

I am trying to create a database using variables, so that the variables can be passed in when the script is run. But when I run the code below I keep on getting an error - any clues what I have done wrong? I’ve not used variables before, so sorry if it is obvious.

(NB The script was creating using the auto-create functions within SQL server)



DECLARE @database varchar(30)

SET @database = 'TESTdb'


USE [master]
GO

CREATE DATABASE [@database] ON PRIMARY
( NAME = N''+@database+'_dat', FILENAME = N'D:Data'+@database+'.mdf' , SIZE = 1932672KB , MAXSIZE = UNLIMITED, FILEGROWTH = 20%)
LOG ON
( NAME = N''+@database+'_log', FILENAME = N'L:LOGS'+@database+'_log.LDF' , SIZE = 8653056KB , MAXSIZE = UNLIMITED, FILEGROWTH = 20%)
COLLATE Latin1_General_CI_AS
